Passage 3.24.5
ἱερὰ δὲ αὐτόθι τὸ μέν ἐστιν Ἀσκληπιοῦ, τὸ δὲ Ἀχιλλέως, καὶ ἑορτὴν κατὰ ἔτος ἄγουσιν Ἀχιλλεῖ. ἄκρα δέ ἐστιν ἐν ταῖς Βρασιαῖς μικρά, προέχουσα ἠρέμα ἐς τὴν θάλασσαν, καὶ ἐπʼ αὐτῇ χαλκοῖ ποδιαίων ἑστήκασιν οὐ μείζονες, πίλους ἐπὶ ταῖς κεφαλαῖς ἔχοντες, οὐκ οἶδα εἰ Διοσκούρους σφᾶς ἢ Κορύβαντας νομίζουσι· τρεῖς δʼ οὖν εἰσί, τέταρτον δὲ Ἀθηνᾶς ἄγαλμα.
There are sanctuaries here, one of Asclepius, the other of Achilles; they also celebrate a festival for Achilles each year. At Brasiai there is a small promontory, gently extending into the sea. Upon it stand bronze figures of foot-high size, wearing caps upon their heads. I do not know whether the locals consider them Dioscuri or Corybantes—there are indeed three of them, and a fourth statue represents Athena.
