Strabo Geography 9.3.13

[13] On the seacoast after Anticyra, one comes first to a town called Opisthomarathus; then to a cape called Pharygium, where there is an anchoring-place; then to the harbor that is last, which, from the fact in the case, is called Mychus; ¹ and it lies below Helicon and Ascre. And the oracle of Abae is not far from this region, nor Ambrysus, nor Medeon, ² which bears the same name as the Boeotian Medeon. Still farther in the interior, after Delphi, approximately towards the east, is a town Daulis, where Tereus the Thracian is said to have held sway (the scene of the mythical story of Philomela and Procne is laid there, though Thucydides ³ says at Megara). The place got its name from the thickets, for they call thickets “dauli.” Now Homer called it Daulis, but later writers call it Daulia. And “Cyparissus,” in the words ⁴ is interpreted by writers in two ways, by some as bearing the same name as the tree, ⁵ and by others, by a slight change in the spelling, as a village below Lycoreia. ⁶

[13] Immediately on the sea-coast, next after Anticyra, ¹ and behind ² it, is the small city Marathus; then a promontory, Pharygium, which has a shelter for vessels; then the harbour at the farthest end, called Mychus, ³ from the accident of its situation between Helicon ⁴ and Ascra.

Nor is Abae, ⁵ the seat of an oracle, far from these places, nor Ambrysus, ⁶ nor Medeon, of the same name as a city in Boeotia.

In the inland parts, next after Delphi, towards the east is Daulis, ⁷ a small town, where, it is said, Tereus, the Thracian, was prince; and there they say is the scene of the fable of Philomela and Procne; Thucydides lays it there; but other writers refer it to Megara. The name of the place is derived from the thickets there, for they call thickets Dauli. Homer calls it Daulis, but subsequent writers Daulia, and the words are understood in a double sense; some persons supposing it to have its name from the tree of the country, but others from a village situated below the Lycoreian territory.
