Passage 6.24.2
ἡ δὲ ἀγορὰ τοῖς Ἠλείοις οὐ κατὰ τὰς Ἰώνων καὶ ὅσαι πρὸς Ἰωνίᾳ πόλεις εἰσὶν Ἑλλήνων, τρόπῳ δὲ πεποίηται τῷ ἀρχαιοτέρῳ στοαῖς τε ἀπὸ ἀλλήλων διεστώσαις καὶ ἀγυιαῖς διʼ αὐτῶν. ὄνομα δὲ τῇ ἀγορᾷ τὸ ἐφʼ ἡμῶν ἐστιν Ἱππόδρομος, καὶ οἱ ἐπιχώριοι τοὺς ἵππους παιδεύουσιν ἐνταῦθα. τῶν στοῶν δὲ ἡ πρὸς μεσημβρίαν ἐργασίας ἐστὶ τῆς Δωρίου, διαιροῦσι δὲ αὐτὴν ἐς μοίρας τρεῖς οἱ κίονες· ἐν ταύτῃ διημερεύουσι τὰ πολλὰ οἱ Ἑλλανοδίκαι.
The market-place of the Eleans is not constructed after the fashion of the Ionians, or that of the Greek cities near Ionia, but is built in a more ancient style, with colonnades separated from one another and streets running through them. The market-place is called, in our time, the Hippodrome, and here the local inhabitants train their horses. Of the porticoes, the southern is the work of Doricus; the columns divide it into three sections. Here the Hellanodikai generally spend their days.
