Pausania, De Graecia Descriptio
VIII, 2, 1-4
Lycaon the son of Pelasgus devised the following plans, which were clever than those of his father the founded the city Lycosura on Mont Lycaciis, gave to Zeus surname Lycaciis and founded the Lycaean games. I hold that the Panatheian festival was not founded before the Lycaean. The early name for the former festival was the Athenian which was changed to the Panatheian in the time of Theseus, because it was then established by the whole Athenian people gathered together in a single city...........................................
My view is that Lycaon was contemporary with cecrops, the King of Athens, butthat they were not equally wise in matters of religion. For Cecrops the first to name Zeus the Supreme god, and refused to sacrifice anything that had life in it, but burnt instead on the altar the Natural cakes which the Athenians still call pelanoi. But Lycaon brought a human baby to the altar Lycaean Zeus, and sacrificed it, pouring out its blood upon the altar, and according to the legend immediatly after the sacrifice he was changed from a man to a wolf. I for my part believe this story; it has been a legend the Arcadians from of old and it has the additional merit of probability. For the men of those days, because of their righteousness and piety were guests of the gods, eating at the same board; the good were openly honoured by the goods, and sinners were openly visited with their wrath......................................................
So one might believe that Lycaon was turned into a beast..............................
It is said, for instance, that ever since the time of Lycaon a man has changed into a wolf at the sacrifice to Lycaean Zeus, but that the change is not for life; if, when he is a wolf, he abstains from human flesh, after nine years he becomes a man again, but if he tastes human flesh he remains a beast for ever
