"[11] (...) Priene is by some writers called Cadme, since Philotas, who founded it, was a Boeotian. Bias, one of the Seven Wise Men, was a native of Priene, of whom Hipponax says stronger in the pleading of his cases than Bias of Priene."

Strabo, 14.1.11

"(...) that the Maeander, flowing through the land of the Phrygians and Carians, which is ploughed up each year, has turned to mainland in a short time the sea that once was between Priene and Miletus."

Pausanias 8.24.11

"[1]The Ionians then came there with their ships manned, and with them the Aeolians who dwell in Lesbos.
This was their order of battle:
The Milesians themselves had the eastern wing, bringing eighty ships; next to them were the Prieneans with twelve ships, and the Myesians with three; next to the Myesians were the Teians with seventeen ships; next to these the Chians with a hundred; near these in the line were the Erythraeans, bringing eight ships, and the Phocaeans with three, and next to these the Lesbians with seventy; last of all in the line were the Samians, holding the western wing with sixty ships.
[2] The total number of all these together was three hundred and fifty-three triremes."

(Describing of the Seabattle of Lade)

Herodotus, 6.8.1-2

"[10] The Ionians who settled at Myus and Priene, they too took the cities from Carians. The founder of Myus was Cyaretus the son of Codrus, but the people of Priene, half Theban and half Ionian, had as their founders Philotas, the descendant of Peneleus, and Aepytus, the son of Neileus. The people of Priene, although they suffered much at the hands of Tabutes the Persian and afterwards at the hands of Hiero, a native, yet down to the present day are accounted Ionians. (...)

Pausanias 7.2.10

"[3] They do not all have the same speech but four different dialects. Miletus lies farthest south among them, and next to it come Myus and Priene; these are settlements in Caria, and they have a common language; Ephesus, Colophon, Lebedos, Teos, Clazomenae, Phocaea, all of them in Lydia,
[4] have a language in common which is wholly different from the speech of the three former cities. There are yet three Ionian cities, two of them situated on the islands of Samos and Chios, and one, Erythrae, on the mainland; the Chians and Erythraeans speak alike, but the Samians have a language which is their own and no one else's. It is thus seen that there are four modes of speech."

Herodotus, 1.142.3
