It is said to have derived its name from the woody character of the district, since δαυλός was used by the inhabitants instead of δαλός, while others sought for the origin of the name in the mythical nymph Daulis, a daughter of Cephissus.
[10][11] In 198 BCE, the Romans besieged Daulis but, not being able to take it by direct assault since the city had a very strong position on the top of a hill, they had to occupy it by a stratagem.
[13] The name of Daulis is still preserved in that of the modern village of Davleia, situated in a narrow valley, through which flows a branch of the Cephissus (Platania).
The walls of the acropolis may be traced on the summit of the height rising opposite the modern village, and connected with the foot of Parnassus by a narrow isthmus.
Before the door of the church in the modern village is another ancient inscription, of considerable length, recording an arbitration made at Chaeroneia in the reign of Hadrian, concerning certain property in Daulis.
