Passage 5.23.1
παρεξιόντι δὲ παρὰ τὴν ἐς τὸ βουλευτήριον ἔσοδον Ζεύς τε ἕστηκεν ἐπίγραμμα ἔχων οὐδὲν καὶ αὖθις ὡς πρὸς ἄρκτον ἐπιστρέψαντι ἄγαλμά ἐστι Διός· τοῦτο τέτραπται μὲν πρὸς ἀνίσχοντα ἥλιον, ἀνέθεσαν δὲ Ἑλλήνων ὅσοι Πλαταιᾶσιν ἐμαχέσαντο ἐναντία Μαρδονίου τε καὶ Μήδων. εἰσὶ δὲ καὶ ἐγγεγραμμέναι κατὰ τοῦ βάθρου τὰ δεξιὰ αἱ μετασχοῦσαι πόλεις τοῦ ἔργου, Λακεδαιμόνιοι μὲν πρῶτοι, μετὰ δὲ αὐτοὺς Ἀθηναῖοι, τρίτοι δὲ γεγραμμένοι καὶ τέταρτοι Κορίνθιοί τε καὶ Σικυώνιοι,
As you pass by the entrance to the Council-chamber, there stands a statue of Zeus, bearing no inscription. Turning further toward the north, there is another statue of Zeus; this one faces the rising sun, and was dedicated by those Greeks who fought at Plataea against Mardonius and the Medes. Upon the right side of its pedestal are inscribed the names of the cities that took part in the battle: first come the Lacedaemonians, next after them the Athenians; third and fourth listed are the Corinthians and the Sicyonians.
