Daulis was the hometown of Tereus, Thracian king and also the city at the end of the road not taken by Oedipus.
[1] According to Homer, it was said to be named either in reference to the woody character of the area or after a nymph Daulis, a daughter of the river-god Cephissus.
The hoopoe, into which the legend says Tereus was changed, is a bird a little larger than the quail, while the feathers on its head rise into the shape of a crest.It is noteworthy that in Phocis swallows neither hatch nor lay eggs; in fact no swallow would even make a nest in the roof of a house.
The wooden image, of an even earlier date, the Daulians say was brought from Athens by Procne.In the territory of Daulis is a place called Tronis.
At any rate, he is worshipped every day, and the Phocians bring victims and pour the blood into the grave through a hole, but the flesh they are wont to consume on the spot."
