Life of Theokritos, 1b
Others says that bucolic poetry was first performed at Tyndaris in Sicily. When Orestes took the image of Artemis away from Tauris in Scythia, he received an oracle, that he should wash himself in seven rivers flowing from one source. Therefore Orestes went to Rhegium in Italy, and washed away the curse in the so-called “separated” rivers. Then he crossed over to Tyndaris in Sicily, where the inhabitants sang their local songs in honour of the goddess, and this was the origin of the tradition. They say that when the men sang, they prepared a loaf with many images of wild animals on it, a pouch full of all kinds of seeds, and wine in a goatskin, to pour out as an offering for those they met. They wore a garland, with the antlers of a deer [on their head], and a staff in their hands. The victor in the contest received the loaf of the man he had vanquished; and the victor remained in the city of Syracuse, while the losers went out to the surrounding villages to collect food for themselves. They sang songs full of fun and laughter, and added the following propitious words:
Receive good fortune,
Receive good health,
Which we bring from the goddess,
Which she has commanded.
