Across the river and ahead, small herbaceous flowers of white, yellow, and purple, blending into the half-grown grass bright green with new life, extended to the horizon. But the child had no eyes for the fleeting spring beauty of the steppes. Weakness and hunger were making her delirious. She started hallucinating.

“I said I’d be careful, mother. I only swam a little ways, but where did you go?” she muttered. “Mother, when are we going to eat? I’m so hungry, and it’s hot. Why didn’t you come when I called you? I called and called, but you never came. Where have you been? Mother? Mother! Don’t go away again! Stay here! Mother, wait for me! Don’t leave me!”

She ran in the direction of the mirage as the vision faded, following the base of the cliff, but the cliff was pulling back from the water’s edge, veering away from the river. She was leaving her source of water. Running blindly, she stubbed her toe on a rock and fell hard. It jarred her back to reality-almost. She sat rubbing her toe, trying to collect her thoughts.

The jagged sandstone wall was pockmarked with dark holes of caves and streaked with narrow cracks and crevices. Expansion and contraction from extremes of searing heat and subzero cold had crumbled the soft rock. The child looked into a small hole near the ground in the wall beside her, but the tiny cave made little impression.

Far more impressive was the herd of aurochs grazing peacefully on the lush new grass between the cliff and the river. In her blind rush to follow a mirage, she hadn’t noticed the huge reddish brown wild cattle, six feet high at the withers with immense curving horns. When she did, sudden fear cleared the last cobwebs from her brain. She backed closer to the rock wall, keeping her eye on a burly bull that had stopped grazing to watch her, then she turned and started running.
