We learn from Stephanus that Eutresis possessed a celebrated temple and oracle of Apollo, who was hence surnamed Eutresites.

[3] The Periplus of Pseudo-Scylax, in its description of the coast of Boeotia, speaks of ὁ λιμὴν Εὔτρητος καὶ τεῖχος τῶν Βοιωτῶν.

The archeology shows that the place was abandoned in the last phase of the Mycenaean period and again populated from the 6th century BCE onwards.

[7] In one of the Mycenaean clay tablets with inscriptions in Linear B script that were found in Thebes in 1995, the toponym Eutresis is written in the form "e-u-te-re-u".

According to the archaeologist Vassilis Aravantinos, at that time, Eutresis should be the second largest town in the area controlled by the palace of Thebes, after the capital.
