Theseus

When the lot was cast, Theseus took those upon whom it fell from the prytaneium and went to the Delphinium, where he dedicated to Apollo in their behalf his suppliant’s badge. This was a bough from the sacred olive-tree, wreathed with white wool. Having made his vows and prayers, he went down to the sea on the sixth day of the month Munychion, on which day even now the Athenians still send their maidens to the Delphinium to propitiate the god.

And it is reported that the god at Delphi commanded him in an oracle to make Aphrodite his guide, and invite her to attend him on his journey, and that as he sacrificed the usual she-goat to her by the sea-shore, it became a he-goat ( tragos) all at once, for which reason the goddess has the surname Epitragia.
