A few yards from where he journeyed he saw de Bono lying asleep on the grass, his mouth open like a fish's mouth. He moved towards the sleeper to question him, but before he reached the man something else drew his attention. Mere yards from where de Bono lay there were shafts of light springing up from the dark ground. He moved over his companion's body, his light almost stirring de Bono, then on towards this new mystery.

It was easily solved. There were several holes in the earth. He went to the lip of the nearest and peered down. The entire mountain, he now saw, was hollow. Below him was a vast cavern, with brightnesses moving in it. These were, presumably, the presences of which de Bono had spoken.

Now the suspicion that he'd left his body behind him somewhere along the way was confirmed, for he slipped down the hole - which would not have been wide enough to allow access to his head never mind his shoulders - and fell into the upper air of the cavern.

There he hovered, and gazed on the ritual being performed below.

At first sight the performers seemed to be spheres of luminous gas, perhaps forty of them, some large, some minute, their colours ranging from cool pastels through to livid yellows and reds. But as he drifted down from the dome of the cavern, claimed not by gravity but by the simple desire to know, he realized that the globes were far from blank. Within their confines forms were appearing, like ghosts in their perfect geometries. They were ephemeral, these visions, lasting seconds at most, before pale clouds veiled them and new configurations took their place. But they lingered long enough for him to make sense of them.

In several of the spheres he saw shapes that resembled human foetuses, their heads vast, their thread-like limbs wrapped about their bodies. No sooner seen than gone; and in their place perhaps a splash of bright blue, that made the globe into a vast eyeball. In another, the gases were dividing and dividing, like a cell in love with itself; in a third the clouds had become a blizzard, in the depths of which he saw a forest and a hill.

He was certain these entities were aware of his being in the cavern, though none broke the regime of their motion to welcome him. He was not offended by this. Their dance was elaborate, and it would cause no little confusion if one of them were to move off its course. There was an exquisite inevitability about their motion - some of the spheres repeatedly moving within a hair's breadth of collision, then swinging wide an instant before disaster struck; others proceeding in families which described complex paths around each other while simultaneously moving in the great circle that was pivoted at the centre of the cavern.

There was more to fascinate him here than the tranquil majesty of the dance, however, for twice in the flux of one of the larger spheres he glimpsed an image which carried an extraordinary erotic charge. A naked woman, her limbs defying all the laws of anatomy, was floating on a pillow of cloud, her position one of pure sexual display. As Cal witnessed her she was gone, leaving him with the image of her invitation: her lips, her cunt, her buttocks. There was nothing whorish in her exhibition; the crime would have been in shame, which had no place in this charmed circle. The presences were too in love with being for such nonsenses.

They loved death too, and as unequivocally. One sphere had a corpse in its midst, rotted and crawling with flies, disclosed with the same delight as its companion glories.

But death did not interest Cal; the woman did.

Can't do anything tonight - de Bono had said - except love, and Cal knew it now to be true.

But love as he'd known it above ground was not appropriate here. The woman in the sphere needed no sweet-talk; her company was offered freely. The question was: how did he express his desire? He'd left his erection behind on Venus Mountain.

He needn't have concerned himself: she already knew his thoughts. As his eyes found her a third time, her glance seemed to draw him down into the midst of the dance. He found himself executing a slow, slow somersault, and settling into place beside his mistress.

As he attained this spot, he realized just what function he had here.

The voice on the mountain had called him Mooney, and that name had not been chosen in vain. He had come from above as light, as moonlight, and here he had found his orbit in a dance of planets and satellites.

Perhaps, of course, this was simply his interpretation. Perhaps the imperatives of this system pertained as much to love and snow-storms as to astronomy. In the face of such miracles conjecture was fruitless. Tonight, being was all.

The presences made another circuit, and he, lost in the sheer delight of this preordained journey, tumbling over and over (no heels or head here; only the pleasure of motion), was momentarily distracted from the woman he'd seen. But as his orbit took him out in a wide arc he once more set eyes on the planet she haunted. She emerged even as he watched, only to be lost in cloud again. Did he perform the same rites for her, turning from humanity to abstraction and back again at the blossoming of a milky cloud? He knew so little of himself, this Mooney, in his singular orbit.

All he could hope to comprehend of what he was he had to discover from the spheres upon whose faces he shed his borrowed light. That was perhaps the condition of moons.

It was enough.

He knew in that moment how moons made love. By bewitching the nights of planets; by stirring their oceans; by blessing the hunter and the harvester. A hundred ways that needed only the unbound anatomies of light and space.

As he thought this thought the woman opened to bathe in him, to spread her cunt and let his light pleasure her.

Entering, he felt the same heat, the same possessiveness, the same vanity as had ever marked the animal he'd been, but in place of labour there was ease, in place of ever imminent loss, sustenance; in place of urgency the sense that this could last forever, or rather that a hundred human lifetimes were a moment in the span of moons, and his ride on this empyrean carousel had made a nonsense of time.

At that thought a terrible sense of poignancy swept over him. Had all he'd left above on the mountain withered and died while these constellations moved steadily about their business?

He looked towards the centre of the system, the hub about which they all described their paths - eccentric or regular, distant or intimate; and there, in the place from which he drew his light, he saw himself, sleeping on a hillside.

I'm dreaming, he thought, and suddenly rose - like a bubble in a bottle - less moon than Mooney. The dome of the cavern - which he vaguely realized resembled the inside of a skull -was dark above him, and for an instant he thought he'd be dashed to death against it, but at the last moment the air grew bright around him and he woke, staring up at a sky streaked with light.

It was dawn on Venus Mountain.

Of the dream he'd had, one part was true. He had sloughed off two skins like a snake. One, his clothes, lay scattered around him in the grass. The other, the accrued grime of his adventures, had been bathed away in the night, either by dew or a fall of rain. Whichever, he was quite dry now; the warmth of the ground he lay upon (that part also had been no dream) had dried him off and left him sweet-smelling. He felt nourished too, and strong. He sat up. Balm de Bono was already on his feet, scratching his balls and staring up at the sky: a blissful combination. The grass had left an imprint on his back and buttocks.

'Did they please you?' he said, cocking an eye at Cal.

'Please me?'

'The Presences. Did they give you sweet dreams?'

'Yes they did.'

De Bono grinned lewdly.

'Want to tell me about it?' he said.

'I don't know how to -'

'Oh spare me the modesty.'

'No, it's just I... I dreamt I was ... the moon.'

'You did what?'

'I dreamt -'

'I bring you to the nearest thing we've got to a whorehouse, and you dream about being the moon? You're a strange man, Calhoun.'

He picked up his vest, and put it on, shaking his head at Cal's bizarrity.

'What did you dream of?' Cal enquired.

'I'll tell you, one of these times,' said de Bono. 'When you're old enough.'

They dressed in silence, then set off down the gentle slope of the mountain.
