Theiodamas

Meantime Hylas with pitcher of bronze in hand had gone apart from the throng, seeking the sacred flow of a fountain, that he might be quick in drawing water for the evening meal and actively make all things ready in due order against his lord's return. For in such ways did Heracles nurture him from his first childhood when he had carried him off from the house of his father, goodly Theiodamas, whom the hero pitilessly slew among the Dryopians because he withstood him about an ox for the plough. Theiodamas was cleaving with his plough the soil of fallow land when he was smitten with the curse; and Heracles bade him give up the ploughing ox against his will. For he desired to find some pretext for war against the Dryopians for their bane, since they dwelt there reckless of right. But these tales would lead me far astray from my song. And quickly Hylas came to the spring which the people who dwell thereabouts call Pegae.
