The three daughters
of king Anius of Delos and Dryope, and granddaughters of Staphylos.
Their names were Oeno (wine), Spermo (wheat) and Elais (oliveoil).
Their grandfather was Dionysus, and he gave them the powers to change water into wine, grass into wheat and berries into olives. For this reason noone around them ever had to starve.
When the Greek fleet set out to make war in Troy, it was the Oenotropae who stocked their ships, and Agamemnon was so impressed with this that he wanted to abduct them.
Dionysus saved them, though, by turning them into doves.
