And in the tank, the center of the picture, a great horse, bright bay and wet and ruddy satin, vertical in the water, struck upward and outward into the free air with huge fore-hoofs steel-gleaming in the wet and sun, while on its back, slipping and clinging, was the white form of what Graham took at first to be some glorious youth. Not until the stallion, sinking, emerged again by means of the powerful beat of his legs and hoofs, did Graham realize that it was a woman who rode him--a woman as white as the white silken slip of a bathing suit that molded to her form like a marble-carven veiling of drapery. As marble was her back, save that the fine delicate muscles moved and crept under the silken suit as she strove to keep her head above water. Her slim round arms were twined in yards of half-drowned stallion-mane, while her white round knees slipped on the sleek, wet, satin pads of the great horse's straining shoulder muscles. The white toes of her dug for a grip into the smooth sides of the animal, vainly seeking a hold on the ribs beneath. In a breath, or the half of a breath, Graham saw the whole breathless situation, realized that the white wonderful creature was a woman, and sensed the smallness and daintiness of her despite her gladiatorial struggles. She reminded him of some Dresden china figure set absurdly small and light and strangely on the drowning back of a titanic beast. So dwarfed was she by the bulk of the stallion that she was a midget, or a tiny fairy from fairyland come true. As she pressed her cheek against the great arching neck, her golden-brown hair, wet from being under, flowing and tangled, seemed tangled in the black mane of the stallion. But it was her face that smote Graham most of all. It was a boy's face; it was a woman's face; it was serious and at the same time amused, expressing the pleasure it found woven with the peril. It was a white woman's face--and modern; and yet, to Graham, it was all-pagan. This was not a creature and a situation one happened upon in the twentieth century. It was straight out of old Greece. It was a Maxfield Parrish reminiscence from the Arabian Nights. Genii might be expected to rise from those troubled depths, or golden princes, astride winged dragons, to swoop down out of the blue to the rescue. The stallion, forcing itself higher out of water, missed, by a shade, from turning over backward as it sank. Glorious animal and glorious rider disappeared together beneath the surface, to rise together, a second later, the stallion still pawing the air with fore-hoofs the size of dinner plates, the rider still clinging to the sleek, satin-coated muscles. Graham thought, with a gasp, what might have happened had the stallion turned over. A chance blow from any one of those four enormous floundering hoofs could have put out and quenched forever the light and sparkle of that superb, white-bodied, fire-animated woman.
