And the subcommittee on terraforming had recommended, and the General Assembly approved, a whole package of terraforming efforts, among them the distribution on the surface of genetically engineered micro-organisms, GEMs constructed from parent stock such as algaes, bacteria, or lichens.

Arkady laughed for a good thirty seconds. “Those bastards, those lucky bastards! They’re going to get away with it.”

PART FOUR Homesick (#ulink_dcb92544-6ae6-506e-8555-58514cd4d7c8)

One winter morning the sun shines down on Valles Marineris, illuminating the north walls of all the canyons in that great concatenation of canyons. And in that bright light, all day every day, one can see that every ledge and outcropping is black with a warty surface of lichen.

Life adapts, you see. It has only a few needs, some fuel, some energy; and it is fantastically ingenious at extracting these needs from a wide range of environments. Some Terran organisms live always below the freezing point of water, others above the boiling point; some live in high radiation zones, others in intensely salty regions, or within solid rock, or in pitch black, or in extreme dehydration, or without oxygen. All kinds of environments are accommodated, by adaptive measures so strange and marvelous they are beyond our capacity to imagine; and so from the bedrock to high in the atmosphere, life has permeated the Earth with the full weave of one great biosphere.

All these adaptive abilities are coded and passed along in genes. If the genes mutate, the organisms change. If the genes are altered, the organisms change. Bioengineers use both these forms of change, not only recombinant gene splicing, but also the much older art of selective breeding. Micro-organisms are plated, and the fastest growers (or those that exhibit most the trait you want) can be culled and plated again; mutagens can be added to increase the mutation rate; and in the quick succession of microbial generations (say ten per day), you can repeat this process until you get something like what you want. Selective breeding is one of the most powerful bioengineering techniques we have.

But the newer techniques tend to get the attention. Genetically engineered micro-organisms had been on the scene only about half a century when the first hundred arrived on Mars. But half a century in modern science is a long time. Plasmid conjugates had become very sophisticated tools in those years. The array of restriction enzymes for cutting, and ligase enzymes for pasting, was big and versatile; the ability to line out long DNA strings precisely was there; the accumulated knowledge of genomes was immense, and growing exponentially; and used all together, this new biotechnology was allowing all kinds of trait mobilization, promotion, replication, triggered suicide (to stop excess success), and so forth. It was possible to find the DNA sequences from an organism that carried the desired characteristic, and then synthesize these DNA messages and cut and paste them into plasmid rings; after that cells were washed and suspended in a glycerol with the new plasmids, and the glycerol was suspended between two electrodes and given a short sharp shock of about two thousand volts: the plasmids in the glycerol shot into the cells, and voila! There, zapped to life like Frankenstein’s monster, was a new organism. With new abilities.

And so: fast-growing lichens. Radiation-resistant algae. Extreme-cold fungi. Halophylic bacteria, eating salt and excreting oxygen. Surarctic mosses. An entire taxonomy of new kinds of life, all partially adapted to the surface of Mars, all out there having a try at it. Some species went extinct: natural selection. Some prospered: survival of the fittest. Some prospered wildly, at the expense of other organisms; and then chemicals in their excretions activated their suicide genes, and they died back until the levels of those chemicals dropped again.

So life adapts to conditions. And at the same time, conditions are changed by life. That is one of the definitions of life: organism and environment change together in a reciprocal arrangement, as they are two manifestations of an ecology, two parts of a whole.

And so: black fuzz on the polar ice. Black fuzz on the ragged surfaces of bubbled rock. Pale green patches on the ground. Bigger grains of frost in the air. Animacules shoving through the depths of the regolith, like trillions of tiny moles.

At first it was nearly invisible, and very slow. With a cold snap or a solar storm there would be massive die-offs, whole species extinct in a night. But the remains of the dead fed other creatures; conditions were thus easier for them, and the process picked up momentum. Bacteria reproduce quickly, doubling their mass many times a day if conditions are right: the mathematical possibilities for the speed of their growth are staggering, and although environmental constraints – especially on Mars – keep all actual growth far from the mathematical limits, still, the new organisms, the areophytes, quickly reproduced, sometimes mutated, always died, and the new life fed on the compost of their ancestors, and reproduced again. Lived and died; and the soil and air left behind were different than they were before these millions of brief generations.

And so one morning the sun rises, shooting long rays through the ragged cloud cover, up the length of Valles Marineris. On the north wall every horizontal face is black and yellow and olive and gray and green, all with the warty surfaces of lichen. Plates of lichen drip down the vertical faces of stone, which stand as they always have, stony, and cracked, and red; but now mottled, as if with lace.

Michel Duval dreamed of home. He was swimming in the surf off the point at Villefranche-sur-Mer, the warm August water lifting him up and down. It was windy and near sunset and the water was a sloppy white bronze, the sunlight bouncing all over it. The waves were big for the Mediterranean, swift breakers that rose up all riven with wind chop to crash in quick uneven lines, allowing him to ride them for a moment. Then it was under in a tumble of bubbles and sand, and back up into a burst of gold light and the taste of salt in everything, his eyes stinging voluptuously. Big black pelicans rode air cushions just over the swells, soared into steep clumsy turns, stalled, dropped into the water around him. They half-folded their wings when they dove, making adjustments with them until the actual moment of the awkward crash into the water. Often they came up gulping small fish. Just meters from him one splashed in, silhouetted against the sun like a Stuka or a pterodactyl. Cool and warm, immersed in salt, he bobbed on the swell and blinked, blinded by salt light. A breaking wave looked like diamonds smashed to cream.

His phone rang.

His phone rang. It was Ursula and Phyllis, to tell him that Maya was having another fit and was inconsolable. He got up, put on unders and went to the bathroom. Waves leaped over a line of backwash. Maya, depressed again. Last time he had seen her she had been in high spirits, almost euphoric, and that was what, a week ago? But that was Maya. Maya was crazy. Crazy in a Russian way, however, which meant she was a power to be reckoned with. Mother Russia! The church and the communists both had tried to eradicate the matriarchy that had preceded them; and all they had achieved was a flood of bitter emasculating scorn, a whole nation full of contemptuous russalkas and baba yagas and twenty-hour-a-day superwomen, living in a nearly parthenogenic culture of mothers, daughters, babushkas, granddaughters. Yet still necessarily absorbed in their relationships with men, desperately trying to find the lost father, the perfect mate. Or just a man who would pull his share of the load. Finding that great love, and then more often than not destroying it. Crazy!

Well, it was dangerous to generalize. But Maya was a classic case. Moody, angry, flirtatious, brilliant, charming, manipulative, intense – and now filling his office like a huge slab of dejection, her eyes red-rimmed and bloodshot, her mouth haggard. Ursula and Phyllis nodded and whispered thanks to Michel for getting up so early, and left. He went to the Venetian blinds and opened them, and the light from the central dome poured in. He saw again that Maya was a beautiful woman, with wild lustrous hair and a dark charismatic gaze, immediate and direct. It was dismaying to see her this upset, he never got used to it, it contrasted too sharply with her usual vivaciousness, the way she would put a finger to your arm as she rattled on in a confiding tone about one fascinating thing or other …

All strangely mimicked by this desperate creature, who leaned forward onto his desk and began to tell him in a ragged hoarse voice about the latest scene in the unfolding drama of her and John, and then, again, Frank. Apparently she had gotten angry at John for refusing to help her in a plan she had to get some of the Russian-based multinationals to underwrite the development of settlements in Hellas Basin, which being the deepest point on Mars was going to be first to benefit from the atmospheric changes they were beginning to see. The air pressure at Low Point, four kilometers below the datum, was always going to be ten times thicker than that on top of the great volcanoes, and three times thicker than at the datum: it was going to be the first human-viable place, perfect for development.

But apparently John preferred to work through UNOMA and governments. And this was just one of the many basic political disagreements which were beginning to infect their personal life, to the point that they were fighting pretty frequently about other things, things that didn’t matter, things about which they had never fought before.

Watching her Michel almost said, John wants you irritated with him. He wasn’t sure what John would say to that. Maya rubbed her eyes, leaned her forehead on his desk, revealing the back of her neck and her broad rangy shoulders. She would never look this distraught in front of most of Underhill; it was an intimacy between them, something she only did with him. It was as if she had taken off her clothes. People didn’t understand that true intimacy did not consist of sexual intercourse, which could be done with strangers and in a state of total alienation; intimacy consisted of talking for hours about what was most important in one’s life. Although it was true she would be beautiful naked, she had perfect proportions. He recalled the way she looked swimming in the pool, doing the backstroke in a blue bathing suit cut high over the hipbones. A Mediterranean image: he was floating in the water at Villefranche, everything flooded with sunset’s amber light, and he was looking in at the beach where men and women were walking, naked except for the neon triangles of cache-sexe bathing suits – brown-skinned bare-breasted women, walking in pairs like dancers in the sunlight – then dolphins sliced out of the water between him and the beach, their sleek black bodies rounded like the women’s—

But now Maya was talking about Frank. Frank, who had a sixth sense for trouble between John and Maya (six would not be necessary), and who came running to Maya every time he felt the signs, to walk with her and talk about his vision of Mars, which was progressive, exciting, ambitious, everything that John’s was not. “Frank is so much more dynamic than John these days, I don’t know why.”

“Because he agrees with you,” Michel said.

Maya shrugged. “Perhaps that’s all I mean. But we have a chance to build a whole civilization here, we do. But John is so …” Big sigh. “And yet I love him, I really do. But …”

She talked for a while about their past, how their courtship had saved the voyage out from anarchy (or at least ennui), how John’s easy-going stability had been so good for her. How you could count on him. How impressed she had been by his fame, how she had felt that the liaison made her part of world history forever. But now she understood that she herself was going to be part of world history anyway: all of them in the first hundred were. Her voice rose, became faster and more vehement: “I don’t need John for that now, I only need him for how I feel about him, but now we don’t agree on anything and we’re not very much alike, and Frank who has been so careful to hold back no matter what, we agree about almost everything and I’ve been so enthusiastic about that part that I’ve given him the wrong signal again, so he did it again, yesterday in the pool he – he held me, you know, took my arms in his hands—” she crossed her arms and clasped her biceps in her hands, “ — and asked me to leave John for him, which I would never do, and he was shaking, and I said I couldn’t but I was shaking too.” So later she had been on edge, and had started a fight with John, started it so flagrantly that he had gotten truly angry and had left and taken a rover out to Nadia’s arcade, and spent the night there with the construction team; and Frank had come to talk to her again, and when she had (just barely) put him off, Frank had declared he was going to live with the European settlement on the other side of the planet; he who was the colony’s driving force! “And he’ll really do it, he’s not one to threaten. He’s been learning German the way he does, languages are nothing to Frank.”

Michel tried to concentrate on what she was saying. It was difficult, because he knew full well that in a week everything would be different, all the dynamics in that little trio altered beyond recognition. So it was hard to care. What about his troubles? They went much, much deeper; but no one ever listened to him. He walked back and forth in front of the window, reassuring her with the usual questions and comments. The greenery in the atrium was refreshing; it could have been a courtyard in Aries or Villefranche; or suddenly it reminded him of Avignon’s narrow cypress-arched plaza near the Pope’s palace, the plaza and its cafe tables which in the summer just after sunset had just the color of Mars. Taste of olive and red wine …

“Let’s go for a walk,” he said. Standard part of therapy hour. They crossed the atrium and went to the kitchens so Michel could eat a breakfast which he forgot even as he swallowed. We should call eating forgetting, he thought as they walked around the hall to the locks. They put on suits – Maya entering a change room to get her unders on – then checked them and went in the lock and depressurized it and then opened the big outer door and stepped outside.

The diamond chill. For a while they stayed on the sidewalks circling Underhill, taking a tour of the dump and its great salt pyramids. “Do you think they’ll ever find a use for all this salt?” he said.

“Sax is still working on it.”

From time to time Maya went on talking about John and Frank. Michel asked the questions that a shrink program would have asked, Maya answered in the way a Maya program would have answered. Their voices right in each other’s ears, the intimacy of the intercom.

They came to the lichen farm, and Michel stopped to gaze over the trays, to soak in their intense living color. Black snow algae, and then thick mats of otoo lichen, in which the algae symbiote was a blue-green strain that Vlad had just gotten to grow alone; red lichen, which seemed not to be doing well. Superfluous in any case. Yellow lichen, olive lichen, a lichen that looked exactly like battleship paint. Flaky white and lime green lichen – living green! It pulsed in the eye, a rich and improbable desert flower. He had heard Hiroko, looking down at such a growth, say “This is viriditas,” which was Latin for “greening power”. The word had been coined by a Christian mystic of the middle ages, a woman named Hildegard. Viriditas, now adapting to conditions here, and spreading slowly over the lowlands of the northern hemisphere. In the southern summers it did even better; one day it had reached 285° Kelvin, a record high by 12°. The world was changing, Maya remarked as they walked by the flats. “Yes,” Michel said, and could not help adding, “only three hundred years before we reach livable temperatures.”

Maya laughed. She was feeling better. Soon she would be back on a level, or at least crossing through that zone on the way to euphoria. Maya was labile. Stability-lability was the most recent characteristic Michel had been studying in the first hundred; Maya represented the labile extreme.

“Let’s drive out and see the arcade,” she said. Michel agreed, wondering what might happen if they ran into John. They went to the parking lot and checked out a roadrunner. Michel drove the little jeep and listened to Maya talk. Did conversation change when voices were divorced from bodies, planted right in the ears of the listeners by helmet mikes? It was as if one were always on the phone, even when sitting next to the person you were talking to. Or – was this better or worse? – as if you were engaged in telepathy.

The cement road was smooth, and he drove at the road-runner’s top speed of 60 kph. He could just feel the rush of thin air against his faceplate. All that CO

that Sax so wanted to scrub from the atmosphere. Sax would need powerful scrubbers, even more powerful than the lichens; he needed forests, enormous multi-layered halophylic rainforests, trapping enormous loads of carbon in wood, leaves, mulch, peat. He needed peat bogs a hundred meters deep, rain forests a hundred meters tall. He had said as much. It marked Ann’s face just to hear the sound of his voice.

Fifteen minutes’ drive and they came to Nadia’s arcade. The site was still under construction and looked raw and messy, like Underhill in the beginning but on a larger scale. A long mound of burgundy rubble had been excavated from the trench, which ran east and west like Big Man’s grave.

They stood at one end of the great trench. Thirty meters deep, thirty wide, a kilometer long. The south side of the trench was now a wall of glass; the north side of the trench was covered with arrays of filtering mirrors, alternating with wall-mesocosms, Mars jars or terrariums, all of them together a colorful mix, like a tapestry of past and future. Most of the terrariums were filled with spruce trees and other flora that made it resemble the great world-wrapping Terran forest of the sixtieth latitude. Like Nadia Cherneshevsky’s old home in Siberia, in other words. Was this perhaps a sign that she had a touch of his disease? And could he prevail on her to build a Mediterranean?

Nadia was up working on a bulldozer. A woman with her own kind of viriditas. She stopped and came over to talk briefly with them. The project was coming along, she told them calmly. Amazing what one could do with the robot vehicles that were still being sent up from Earth. The concourse was done, and planted with a variety of trees, including a strain of dwarf sequoia already thirty meters tall, nearly as tall as the whole arcade. The three stacked rows of Underhill-style vaulted chambers behind the concourse were installed, their insulation in place. The settlement had just the other day been sealed and heated and pressurized, so that it was possible to work inside it without suits. The three floors were stacked on each other in ever smaller arches, reminding Michel of the Pont du Gard; of course all the architecture here was Roman in origin, so that should not be a surprise. The arches were wider, however, and slighter. Airier in the tolerance of the g.

Nadia went back to work. Such a calm person. Stabile, the very opposite of labile. Low-keyed, private, inward. Couldn’t be less like her old friend Maya; it was good for Maya to be around her. Opposite end of the scale, keep her from flying away. Set an example for her. As in this encounter, where Maya was matching Nadia’s calm tone. And when Nadia went back to work, Maya retained some of that serenity. “I’ll miss Underhill when we move out here,” she said. “Won’t you?”

“I don’t think so,” Michel said. “This will be a lot sunnier.” All three floors of the new habitat would open onto the tall concourse, and have terraced broad balconies on the sunny side of the rooms, so that even though the whole structure faced north and was buried deeper than Underhill, the heliotropic filtered mirrors on the other side of the trench would pour light onto them from dawn to dusk. “I’ll be happy to move. We’ve needed the space from the beginning.”

“But we won’t get all this space to ourselves. There’ll be new people here.”

“Yes. But that will give us space of a different kind.”

She looked thoughtful. “Like John and Frank leaving.”

“Yes. But even that isn’t necessarily a bad thing.” In a larger society, he told her, the claustrophobic village atmosphere of Underhill would begin to dissipate; this would give a better perspective on certain aspects of things. Michel hesitated before continuing, unsure how to say it. Subtlety was dangerous when you were both using a second language, coming at it from different native tongues: possibilities for misunderstanding were all too real. “You must accept the idea that you perhaps do not want to choose between John and Frank. That in fact you want them both. In the context of the first hundred that can only be scandalous. But in a larger world, over time …”

“Hiroko keeps ten men!” she exclaimed angrily.

“Yes, and so do you. So do you. And in a larger world, no one will know or care.”

He went on reassuring her, telling her that she was powerful, that (using Frank’s terms) she was the alpha female of the troop. She disagreed and forced more praise from him until finally she was satiated, and he could suggest they return home.

“Don’t you think it will be a shock to have new people around? Different people?” She was driving, and as she turned to ask him this she almost drove off the road.

“I suppose.” Parties had already landed in Borealis and Acidalia and the videotapes of them had been a shock, you could see it in people’s faces. As if aliens had arrived from space. But so far only Ann and Simon had met with any of them in person, running into a rover expedition north of Noctis Labyrinthus. “Ann said it felt as if someone had stepped out of the TV.”

“My life feels like that all the time,” Maya said sadly.

Michel lifted his eyebrows. The Maya program would not have said that. “What do you mean?”

“Oh, you know. Half the time it seems like one big simulation, don’t you think?”

“No.” He considered it. “I don’t.” It was all too real, in fact – the cold of it seeping up through the rover seat deep into his flesh – inescapably real, inescapably cold. Perhaps as a Russian she didn’t appreciate that. But it was always, always cold. Even at noon on midsummer’s day, with the sun overhead like an open furnace door blazing in the sand-colored sky, the temperature would be at best 260° K, meaning –15°C, cold enough to push through the mesh of a walker and make each move a little diamond pattern of hurt. As they approached Underhill Michel felt the cold pushing through the fabric into his skin, and he felt the too-cool oxygenated air expand out of the mouthpiece deep into his lungs, and he glanced up at the sand horizon and the sand sky and said to himself, I am a diamondback snake, slithering through a red desert of cold stone and dry dust. Someday I will shed my skin like a phoenix in a fire, to become some new creature of the sun, to walk the beach naked and splash in warm salt water …

Back at Underhill he turned on the shrink program in his head and asked Maya if she were feeling better, and she touched her faceplate to his, giving him a brief glimpse of a gaze that was a kiss. “You know I do,” her voice said in his ear. He nodded. “I think I’ll go for another walk, then,” he said, and did not say, But what about me? What will make me feel better? He willed the movement of his legs and walked off. The bleak plain surrounding the base was a vision out of some post-holocaust desolation, a nightmare world; nevertheless he didn’t want to go back into their little warren of artificial light and heated air and carefully deployed colors, colors that he himself had chosen for the most part, utilizing the very latest in color-mood theory, a theory which he now understood to be based on certain root assumptions that did not in fact apply here: the colors were all wrong, or worse, irrelevant. Wallpaper in hell.

The phrase formed in his mind and pushed at his lips. Wallpaper in hell. Wallpaper in hell. Since they’re going to go crazy anyway … Certainly it had been a mistake to have only one psychiatrist along. Every therapist on Earth was also in therapy, it was part of the job, it came with the territory. But his therapist was back in Nice, fifteen timeslipped minutes away at best, and Michel talked to him but he couldn’t help. He didn’t understand, not really; he lived where it was warm and blue, he could go outside, he was (Michel presumed) in reasonably good mental health. While Michel was a doctor in a hospice in a prison in hell; and the doctor was sick.

He hadn’t been able to adapt. People were different in that regard, it was a matter of temperament. Maya, walking toward the lock door, had a temperament quite different from his, which somehow enabled her to be completely at home here. To tell the truth he didn’t think she really noticed her surroundings much in any case. And yet in other ways he and she were similar. It had to do with the lability-stability index, and its particular emotionality; they were both labile. And yet fundamentally they were very different characters; the labile-stabile index had to be considered in combination with the very different set of characteristics grouped under the labels extroversion and introversion. This had been his great discovery of the recent year, and now it structured all his thinking about himself and his charges.

Walking toward the Alchemists’ Quarter, he fit the morning’s events into the gridwork of this new characterological system. Extra version-introversion was one of the best-studied systems of traits in all psychological theory, with great masses of evidence from many different cultures supporting the objective reality of the concept. Not as a simple duality of course; one did not label a person plainly this or that, but rather placed them on a scale, rating them for such qualities as sociability, impulsiveness, changeability, talkativeness, outgoingness, activity, liveliness, excitability, optimism, and so on. These measurements had been done so many times that it was statistically certain that the various traits did indeed hang together, to a degree that exceeded chance by a huge amount. So the concept was real, quite real! In fact physiological investigations had revealed that extraversion was linked with resting states of low cortical arousal, introversion with high cortical arousal; this had sounded backwards to Michel at first, but then he remembered that the cortex inhibits the lower centers of the brain, so that low cortical arousal allows the more uninhibited behavior of the extravert, while high cortical arousal is inhibitory and leads to introversion. This explained why drinking alcohol, a depressant which lowers cortical arousal, could lead to more excited and uninhibited behavior.

So the whole collection of extravert-introvert traits, with all that they said about one’s character, could be traced back to a group of cells in the brain stem called the ascending reticular activating system, the area that ultimately determined levels of cortical arousal. Thus they were driven by biology. There should be no such thing as fate: Ralph Waldo Emerson, a year after his six year-old son died. But biology was fate.

And there was more to Michel’s system; fate, after all, was no simple either-or. He had recently begun to consider Wenger’s index of autonomic balance, which used seven different variables to determine whether an individual was dominated by the sympathetic or the parasympathetic branches of the autonomic nervous system. The sympathetic branch responds to outside stimuli and alerts the organism to action, so that individuals dominated by this branch were excitable; the parasympathetic branch, on the other hand, habituates the alerted organism to the stimulus, and restores it to homeostatic balance, so that individuals dominated by this branch were placid. Duffy had suggested calling these two classes of individuals labiles and stabiles, and this classification, while not as famous as extraversion and introversion, was just as solidly backed by empirical evidence, and just as useful in understanding varieties of temperament.

Now, neither system of classification told the investigator all that much about the total nature of the personality being studied. The terms were so general, they were collections of so many traits, that they said very little in any useful diagnostic sense, especially since both were Gaussian curves in the actual population.

But combine the two systems, and it began to get very interesting indeed.

It was not a simple matter, and Michel had spent a fair amount of time at his computer screen sketching one kind of combinatoire after another, using the two different systems as the x and y axes of several different grids, none of which told him much. But then he began moving the four terms around the initial points of a Greimas semantic rectangle, a structuralist schema with alchemical ancestry, which proposed that no simple dialectic was enough to indicate the true complexity of any cluster of related concepts, so that it was necessary to acknowledge the real difference between something’s opposite and its contrary; the concept “not-X” being not quite the same thing as “anti-X,” as one saw immediately. So the first stage was usually indicated by using the four terms

in a simple rectangle:

Thus —S was a simple not-S, and s was the stronger anti-S; while —s was the for Michel skullcracking negation of a negation, either a neutralizing of the initial opposition, or the union of the two negations; in practice this often remained a mystery or koan, but sometimes it came clear, as an idea that completed the conceptual unit quite nicely, as in one of Greimas’s examples:

The next step in the complication of the design, the step where new combinations often revealed structural relationships not at all obvious on the face of it, was to build another rectangle that bracketed the first at right angles, like so:

And Michel had stared at this schema, with extraversion, introversion, lability and stability at the first four corners, and considered their combinations; and then everything had suddenly fallen into focus, as if a kaleidoscope had suddenly clicked by accident into a depiction of a rose. For it made perfect sense: there were extraverts who were excitable, and extraverts who were on an even keel; there were introverts who were quite emotional, and those who were not. He could immediately think of examples among the colonists of all four of the types.

When considering names to give these combined categories, he had had to laugh. Unbelievable! It was ironic at best to think that he had used the results of a century’s psychological thinking, and some of the latest laboratory research in psychophysiology, not to mention a complicated apparatus from structuralist alchemy, all in order to reinvent the ancient system of the humours. But there it was; that was what it came down to. For the northern combination, extraverted and stabile, was clearly what Hippocrates, Galen, Aristotle, Trimestigus, Wundt, and Jung would have called sanguine; the western point, extraverted and labile, was choleric; in the east, introverted and stabile was phlegmatic; and in the south, introverted and labile was of course the very definition of the melancholic! Yes, they all fit perfectly! Galen’s physiological explanation for the four temperaments had been wrong, of course, and bile, choler, blood and phlegm had now been replaced as causative agents by the ascending reticular activating system and the autonomic nervous system; but the truths of human nature had held fast! And the powers of psychological insight and analytic logic of the first Greek physicians had been as strong, or rather stronger by far, than that of any subsequent generation’s, blinkered by an often-useless accumulation of knowledge; and so the categories had endured and were reaffirmed, in age after age.

Michel found himself in the Alchemists’ Quarter. He exerted himself to pay attention to it. Here men used arcane knowledge to make diamonds out of carbon, and they made it so easily and precisely that all their window glass was coated in a molecular layer of diamond to protect it from the corrosive dust; and their great white salt pyramids (one of the great shapes of ancient knowledge, the pyramid) were coated in layers of pure diamond. And the one-molecule diamond-coating process was just one of thousands of alchemical operations performed in these squat buildings.

In recent years the buildings had taken on a faintly Moslem look, their white brick walls displaying equation after equation, all rendered in black flowing mosaic calligraphy. Michel ran into Sax, who was standing next to the terminal velocity equation displayed on the wall of the brick factory, and he switched to the common band: “Can you turn lead into gold?”

Sax’s helmet tilted quizzically. “Maybe,” he said. “A little of it, anyway. But it would be hard. Let me think about it some.”

Saxifrage Russell. The perfect Phlegmatic.

The really useful part of mapping the four temperaments onto the semantic rectangle was that it immediately suggested a number of basic structural relationships between them, which then helped Michel to see their attractions and antagonisms in a new light. Maya was labile and extraverted, clearly choleric, and so was Frank; and both of them were leaders, and both were quite attracted to the other. Both being choleric, however, there was a volatile and essentially repellent aspect to the relationship as well, as if they recognized in each other exactly what they didn’t like in themselves.

And thus Maya’s love for John, who was clearly sanguine, with an extraversion similar to Maya’s but much more emotionally stabile, even to the point of placidity. So that most of the time he gave her great peace, like an anchor to reality – which then occasionally rankled. And John’s attraction to Maya? The attraction of the unpredictable, perhaps; the spice in his hearty bland happiness. Sure, why not? You can’t make love to your fame. Even though some people try.

Yes, there were a lot of sanguines in the first hundred. Probably the psychological specs for selection to the colony preferred the type. Arkady, Ursula, Phyllis, Spencer, Yeli … Yes. And stability being the most preferred quality for selection, there were naturally a lot of phlegmatics among them as well: Nadia, Sax, Simon Frazier, perhaps Hiroko – the fact that one could not even be sure about her tended to support the guess – Vlad, George, Alex.

Phlegmatics and melancholics would naturally not get along, both being introverted and quick to withdraw, and the stabile one put off by the unpredictability of the labile; so that they would withdraw from each other, like Sax and Ann. There were not many melancholics among them. Ann, yes; and probably by the fate of her brain’s structure, although it did not help that she had been mistreated as a child. She had fallen in love with Mars for the same reason that Michel hated it: because it was dead. And Ann was in love with death.

A few of the alchemists were melancholics as well. And, unfortunately, Michel himself. Perhaps five all told. Along both axes they had been selected against, as neither introversion nor lability had been considered desirable by the selection committee. Only people quite clever at concealing their real nature from the committee could have slipped through, people with great control over their personas, those larger-than-life masks that conceal all the wild inconsistencies within. Perhaps only a certain kind of persona had been selected to the colony, with a wide variety of persons behind it. Was that true? The selection committees had made impossible demands, it was important to remember that. They had wanted stabiles and yet they had wanted people who cared about going to Mars so passionately and monomaniacally that they would devote years of their lives to achieving the goal. Was that consistent? They wanted extraverts and they wanted brilliant scientists who necessarily had had to dive deep into solitary study for years and years. Was that consistent? No! Never. It went on like that all down the list. They had created double bind after double bind, no wonder the first hundred had hidden from them, had hated them! He recalled with a shudder that moment in the great solar storm on the Ares when everyone had realized how much lying and hiding they had had to do, when they had all turned and stared at him with all that pent-up fury, as if it were all his fault, as if he were all psychology, and had concocted the criteria and conducted the tests and made the selections all by himself. How he had cringed at that moment, how alone he had felt! It had shocked him, frightened him, so much that he had not been able to think fast enough to confess that he too had lied, of course he had, more than any of the rest of them!

But why had he lied, why?

This was what he could not quite recall. Melancholia as a failure of memory, an acute sensation of the irreality of the past, its non-existence … He was a melancholic: withdrawn, out of control of his feelings, inclined to depression. He shouldn’t have been chosen to go; and now he could not remember why he had fought so passionately to be chosen. The memory had gone away, overwhelmed perhaps by the poignant, aching, fragmented images of the life he had lived in the interstices of his desire to go to Mars. So minuscule and so precious; the evenings in the plazas, the summer days on the beaches, the nights in women’s beds. The olive trees of Avignon. The green flame cypress.

He found he had left the Alchemists’ Quarter. He was at the foot of the Great Salt Pyramid. He stepped slowly up the four hundred stairs, putting his feet carefully on the blue no-slip pads. Each step gave him a wider view of Underhill Plain, but it was still the same sere and barren rockpile, no matter how large it got. From the square white pavilion at the pyramid’s summit one could just see Chernobyl, and the spaceport. Other than that, nothing. Why had he come to this place? Why had he worked so hard to get here, sacrificing so many of the pleasures of life, family, home, leisure, play … He shook his head. So far as he could recall, it had simply been what he had wanted to do, the definition of his life. A compulsion, a life with a goal, how could you tell the difference? Moonlit nights in the fragrant olive grove, the ground dotted with small black circles and the electric warm brush of the mistral rustling the leaves in quick soft waves, flat on his back, arms spread wide, the leaves flickering silver and grey under the black bowl of stars; and one of those stars would be steady, faint, red, and he would seek it out and watch it, there among the windswept olive leaves; and he had been eight years old! My God, what were they? Nothing explained that, nothing explained them! As well explain why they had painted in Lascaux, why they had built stone cathedrals into the sky. Why coral polyps built reefs.

He had had an ordinary youth, moved often, lost what friends he made, went to the University of Paris to study psychology, did his degree work on space station depression and went to work for Ariane, and then Glavkosmos. Along the way got married and divorced: Françoise had said he “was not there”. All those nights with her in Avignon, all those days in Villefranche-sur-Mer, living in the most beautiful place on Earth, and he had walked about in a fog of desire for Mars! It was absurd! Worse, it was stupid. A failure of the imagination, of memory, of, finally, intelligence itself: he had not been able to see what he had had, or to imagine what he would get. And now he was paying for it, trapped on an icefloe in the Arctic night with ninety-nine foreigners, not one of whom spoke French worth a damn. Only three who could even try, and Frank’s French was worse than no French at all, like listening to someone attack the language with a hatchet.

The absence of his mind’s own tongue had driven him to watching TV from home, which only exacerbated his pain. Still he taped video monologues, and sent them to his mother and sister, so that they would send replies in kind; he watched the replies many times, looking more at the backdrops than at his relatives. He even had occasional live conversations with journalists, waiting impatiently between exchanges. Those talks made it clear how famous he was in France, a household name, and he was careful to answer everything conventionally, playing the Michel Duval persona, running the Michel program. Sometimes he cancelled consultations with fellow colonists when he was in the mood to listen to French; let them eat English! But these incidents got him a sharp reprimand from Frank, and a conference with Maya. Was he overworked? Of course not; only ninety-nine people to keep sane, while at the same time wandering in a Provence of the mind, on tree-covered steep hillsides with their vineyards and farmhouses and ruined towers and monasteries, in a living landscape, a landscape infinitely more beautiful and humane than the stony waste of this reality—

He was in the TV lounge. While lost in thought he had apparently gone back inside. But he could not remember that; he had thought he was still standing on top of the Great Pyramid; and then he had blinked and was in the TV lounge (all asylums have them), watching a video image of one of the lichen-covered canyon walls of Marineris.

He shivered. It had happened again. He had lost touch, gone away and come to later in the day. It had happened already some dozen times before. And it was not just being lost in thought, but buried in it, dead to the world. He looked around the room, shivered convulsively. It was Ls = 5 now, the beginning of northern spring, and the northern walls of the great canyons were basking in the sun. Since they’re all going to go crazy anyway …

Then it was Ls = 157, and 152° had passed in a blur of tele-existence. He was basking in the sun in the courtyard of Françoise’s seaside villa in Villefranche-sur-Mer, looking down on tile rooftops and terracotta pillars and a small pool, turquoise above the cobalt of the Mediterranean. A cypress stood like a green flame over the pool, swaying in a breeze and casting its perfume over his face. In the distance the green headland of a peninsula —

Except really he was in Underhill Prime, usually called the trench, or Nadia’s arcade, sitting on the upper balcony looking out at a dwarf sequoia, behind it the glass wall and the mirrors with their gradient refractive index that guided the light down into the concourse from its origin on the Cote D’Or. Tatiana Durova had been killed by a crane tipped by a robot, and Nadia was inconsolable. But grief runs off us, Michel thought as he sat with her, like rain off a duck. In time Nadia would be well. Meanwhile there was nothing to be done. Did they think he was a sorcerer? A priest? If that were true he would have healed himself, healed all this world, or better, flown through space home. Wouldn’t that cause a sensation, to appear on the beach at Antibes and say, “Bonjour, I am Michel, I have come home”?

Then it was Ls = 190, and he was a lizard on the top of the Pont du Gard, on the narrow rectangular rock plates that covered the actual aqueduct itself, which ran in its straight line high over the gorge. His diamondback skin had sloughed off around his tail, and the hot sun burned the new skin in crisscross lines. Except he was in Underhill in fact, in the atrium, and Frank had gone off to live with the Japanese that had landed in Argyre, and Maya and John were at loggerheads about their rooms, and where to house the UNOMA local headquarters; and Maya, more beautiful than ever, stalked him through the atrium, imploring his aid. He and Marina Tokareva had stopped rooming together nearly a full Martian year before – she had said he was not there – and looking at Maya Michel found himself imagining her as a lover but of course this was crazy, she was a russalka, she had slept with Glavkosmos bosses and cosmonauts to make her way up through the system and it had made her dissociated and bitter and unpredictable, she used sex to hurt now, sex was just diplomacy by other means to her, it would be insane to have anything to do with her in that mode, to be drawn down into the vortex of her limbs and her limbic system. Why not send crazy people in the first place …

But now it was Ls = 241. He walked over the honeycombed limestone parapet of Les Baux, looking in the ruined chambers of the medieval hermitage. It was near sunset and the light was a curious Martian orange, the limestone glowing, the whole village and hazy plain below stretching out to the whitebronze line of the Mediterranean, looking as implausible as a dream … Except it was a dream, and he woke up, and found himself awake and back in Underhill. Phyllis and Edvard had just returned from an expedition and Phyllis was laughing and showing them a buttery lump of rock. “It was scattered all over the canyon,” she said laughing, “gold nuggets the size of your fist.”

Then he was walking the tunnels out to the garage. The colony’s psychiatrist, experiencing visions, falling into gaps of consciousness, gaps of memory. Physician, heal thyself! But he couldn’t. He had gone insane of homesickness. Homesickness, there must be a better term for that, a scientific label that would legitimize it, make it real to others; but he already knew it was real. He missed Provence so much that at times he felt he could not breathe. He was like Nadia’s hand, a part of it torn away, the ghost nerves still throbbing with pain.

… And save them the trouble?

Time passed. The Michel program walked around, a hollow persona, empty inside, only some tiny homunculus of the cerebellum left to teleoperate the thing.

The night of the second day of Ls = 266, he went to bed. He was dog-tired though he had done nothing, totally exhausted and drained, and yet he lay in the dark of his room and could not sleep. His mind spun miserably; he was very aware of how sick he was. He wished he could quit the pretense and admit that he had lost it, institutionalize himself. Go home. He could remember almost nothing of the previous few weeks; or maybe it was longer than that? He was not sure. He began to weep.

His door clicked. It swung open, and a narrow wedge of hall light shone in, unblocked. No one there.

“Hello?” he said, working to keep the tears out of his voice. “Who is it?”

The reply was right in his ear, as if from a helmet intercom: “Come with me,” a man’s voice said.

Michel jerked back and bumped into the wall. He stared up at a black silhouetted figure.

“We need your help,” the figure whispered. A hand gripped his arm as he pressed back into the wall. “And you need ours.” A suggestion of a smile in the voice, which Michel did not recognize.

Fear thrust him into a new world. Suddenly he could see much better, as if the touch of his visitor had sprung his pupils open like camera apertures. A thin dark-skinned man. A stranger. Astonishment launched through his fear, and he got up and moved through the dark light with dreamlike precision, stepping into slippers, and then at the stranger’s urging following him out into the hallway, feeling the lightness of Martian g for the first time in years. The hallway seemed bursting with gray light, though he could tell that only the night strips in the floor were on. It was enough to see well by if you were scared. His companion had short black dreadlocks, which made his head appear spiked. He was short, thin, narrow-faced. A stranger, no doubt about it. An intruder from one of the new colonies in the southern hemisphere, Michel thought. But the man was leading him through Underhill with an expert touch, moving in utter silence. Indeed the whole of Underhill was soundless, as if it were a silent black-and-white film. He glanced at his wristpad: it was blank. The timeslip. He wanted to say, “Who are you?” but the silence was so blanketing that he couldn’t bring himself to speak. He mouthed the words and the man turned and looked over his shoulder at him, the whites of his eyes visible and luminous all the way around the irises, the nostrils wide black holes. “I’m the stowaway,” he mouthed, and grinned. His eyeteeth were discolored; they were made of stone, Michel suddenly saw that. Martian stone teeth in his head. He took Michel by the arm. They were heading to the farm lock. “We need helmets out there,” Michel whispered, balking.

“Not tonight.” The man opened the lock door, and no air rushed into it even though it was open on the other side. They went in and walked between the black rows of packed foliage, and the air was sweet. Hiroko will be angry, Michel thought.

His guide was gone. Ahead Michel saw movement, and heard a tinkly little laugh. It sounded like a child. Suddenly it occurred to Michel that the absence of children accounted for the colony’s pervasive feeling of sterility, that they could build buildings and grow plants and yet without children this sterile feeling would still permeate every part of their lives. Extremely frightened, he continued to walk toward the center of the farm. It was warm and humid, and the air stank of wet dirt and fertilizer and foliage. Light glinted from thousands of leaf surfaces, as if the stars had fallen through the clear roof and clustered around him. Rows of corn rustled, and the air was going to his head like brandy. Little feet were scurrying behind the narrow rice paddies: even in the darkness the rice was an intense blackish green, and there among the paddies were small faces, grinning knee-high and disappearing when he turned to face them. Hot blood flooded his face and hands, his blood turned to fire and he retreated three steps, then stopped and spun. Two naked little girls were walking down the lane toward him, black-haired, dark-skinned, about three years old. Their oriental eyes were bright in the gloom, their expressions solemn. They took him by the hands and turned him around; he allowed them to lead him down the lane, looking down at first one head and then the other. Someone had decided to take action against their sterility. As they walked along, other naked toddlers appeared out of the shrubbery and crowded around them, boys and girls both, some a bit darker or lighter than the first two, most the same color, all the same age. Nine or ten of them escorted Michel to the center of the farm, weaving around him in a quick trot; and there at the center of the maze was a small clearing, currently occupied by about a dozen adults, all naked, seated in a rough circle. The children ran to the adults, gave them hugs and sat at their knees. Michel’s pupils opened further in the nimbus of starlight and leaf gleam, and he recognized members of the farm team, Iwao, Raul, Ellen, Rya, Gene, Evgenia, all of the farm team except for Hiroko herself.

After a moment’s hesitation Michel stepped out of his slippers and took off his clothes, and put them on top of the slippers and sat down in an empty spot in the circle. He didn’t know what he was taking part in, but it didn’t matter. Several of the figures nodded at him in welcome, and Ellen and Evgenia, seated on each side of him, touched him on the arms. All of a sudden the children got up and ran together down one of the aisles, squealing and giggling. They came back in a tight knot around Hiroko, who walked into the middle of the circle, her naked form dark in the darkness. Trailed by the kids she walked slowly around the circle, pouring from her two outstretched fists a little bit of dirt into each person’s offered hands. Michel held up his palms with Ellen and Evgenia as she approached, he stared at her lustrous skin. Once on the night beach at Villefranche he had walked by a gang of African women splashing in the phosphorescent waves, white water on black gleaming skin —

The dirt in his hand was warm and smelled rusty. “This is our body,” Hiroko said. She walked to the other side of the circle, gave the children each a fistful of dirt and sent them back to sit among the adults. She sat across from Michel and began to chant in Japanese. Evgenia leaned over and whispered a translation or rather an explanation in his ear. They were celebrating the areophany, a ceremony they had created together under Hiroko’s guidance and inspiration. It was a kind of landscape religion, a consciousness of Mars as a physical space suffused with kami, which was the spiritual energy or power that rested in the land itself. Kami was manifested most obviously in certain extraordinary objects in the landscape, stone pillars, isolated ejecta, sheer cliffs, oddly smoothed crater interiors, the broad circular peaks of the great volcanoes. These intensified expressions of Mars’s kami had a Terran analogue within the colonists themselves, the power that Hiroko called viriditas, that greening fructiparous power within, which knows that the wild world itself is holy. Kami, viriditas; it was the combination of these sacred powers that would allow humans to exist here in a meaningful way.

When Michel heard Evgenia whisper the word combination, all the terms immediately fell into a semantic rectangle: kami and viriditas, Mars and Earth, hatred and love, absence and yearning. And then the kaleidoscope clicked home and all the rectangles folded into place in his mind, all antimonies collapsed to a single, beautiful rose, the heart of the areophany, kami suffused with viriditas, both fully red and fully green at one and the same time. His jaw was slack, his skin was burning, he could not explain it and did not want to. His blood was fire in his veins.
