One of the elders recalled a similar time from his childhood, when the number of villagers had grown too large and a series of bad years led to hunger and desperation. There was a ritual handed down from a time before his birth, called the rite of sacred spring. A pact was made with the great numina of the sky and the earth: If the village could survive the winter, then, when spring came, a group of children would be driven away from the village, sent forth to survive in the world beyond as best they could.

It seemed a harsh remedy, but times were harsh. The elders advised that there must be a rite of sacred spring. The villagers agreed.

The number of children to be sent away was decided by portent. On a still day, the elders climbed up to a stone promontory on the mountainside above the village. There they set fire to a bundle of dry branches, then stood back and waited until the rising smoke formed a column in the air, so that the sky was separated into two regions, one to either side of the smoke. The elders watched the sky and counted the number of birds that flew from one region to the other, crossing the line defined by the smoke. By the time the branches burned to ashes and the column of smoke dispersed, seven birds were seen to cross. Seven children had to be chosen.

The choosing was done by lottery. It was important that everyone in the village could see that the numina of chance, not the scheming of any parent, dictated the outcome. While everyone in the village watched, the children stood in a line. A pot full of small pebbles, all white except for seven black ones, was passed before them. One by one, the children reached inside and took a pebble. When all of them were done, together they opened their palms to show the stone they had chosen. When it was seen which children had chosen the black pebbles, there was much weeping; but when Cacus’s claw of a hand opened to show a black pebble, even his mother seemed relieved.
