Passage 4.14.1
Μεσσηνίων δὲ ὅσοις μὲν ἔτυχον ἐν Σικυῶνι οὖσαι καὶ ἐν Ἄργει προξενίαι καὶ παρὰ τῶν Ἀρκάδων τισίν, οὗτοι μὲν ἐς ταύτας τὰς πόλεις ἀπεχώρησαν, ἐς Ἐλευσῖνα δὲ οἱ τοῦ γένους τῶν ἱερέων καὶ θεαῖς ταῖς Μεγάλαις τελοῦντες τὰ ὄργια· ὁ δὲ ὄχλος ὁ πολὺς κατὰ τὰς πατρίδας ἕκαστοι τὰς ἀρχαίας ἐσκεδάσθησαν.
Those of the Messenians who happened to have proxenies at Sicyon and Argos, as well as some among the Arcadians, withdrew to those cities; while to Eleusis withdrew those of the priestly lineage and those who performed the rites for the Great Goddesses. The majority of the populace scattered, each group returning to their own ancestral homelands.
