THE SCENE: Remember the time when Hercules had an amorous encounter with a snake-woman and their offspring founded the Scythian people?
THE ACTION: Hercules came from thence into the region now called Scythia, and, being overtaken by storm and frost, drew his lion’s skin about him, and fell fast asleep. While he slept, his mares, which he had loosed from his chariot to graze, by some wonderful chance disappeared.
On waking, he went in quest of them, and he found in a cave a strange being, between a maiden and a serpent, whose form from the waist upwards was like that of a woman, while all below was like a snake. He looked at her wonderingly; but nevertheless inquired, whether she had chanced to see his strayed mares anywhere. She answered him, “Yes, and they were now in her keeping; but never would she consent to give them back, unless he took her for his mistress.” So Hercules, to get his mares back, agreed. At last, when she gave [the mares] up, she said to him, “I bear in my womb three sons of thine. Tell me therefore when thy sons grow up, what must I do with them?” Thus questioned, they say, Hercules answered, “When the lads have grown to manhood, watch them, and when thou seest one of them bend this bow as I now bend it, and gird himself with this girdle thus, choose him to remain in the land. Those who fail in the trial, send away.”
Then he gave both bow and belt into her hands. Now the belt had a golden goblet attached to its clasp. So after he had given them to her, he went his way; and the woman, when her children grew to manhood, first gave them severally their names. One she called Agathyrsus, one Gelonus, and the other, who was the youngest, Scythes. Then she remembered the instructions she had received from Hercules, and, in obedience to his orders, she put her sons to the test. Two of them, Agathyrsus and Gelonus, proving unequal to the task enjoined, their mother sent them out of the land; Scythes, the youngest, succeeded, and so he was allowed to remain. From Scythes, the son of Hercules, were descended the after kings of Scythia; and from the circumstance of the goblet which hung from the belt, the Scythians to this day wear goblets at their girdles.
