Passage 5.12.5
ἀναθήματα δὲ ὁπόσα ἔνδον ἢ ἐν τῷ προνάῳ κεῖται, θρόνος ἐστὶν Ἀριμνήστου βασιλεύσαντος ἐν Τυρσηνοῖς, ὃς πρῶτος βαρβάρων ἀναθήματι τὸν ἐν Ὀλυμπίᾳ Δία ἐδωρήσατο, καὶ ἵπποι Κυνίσκας χαλκοῖ, σημεῖα Ὀλυμπικῆς νίκης· οὗτοι μέγεθος μὲν ἀποδέουσιν ἵππων, ἑστήκασι δὲ ἐν τῷ προνάῳ τοῖς ἐσιοῦσιν ἐν δεξιᾷ. κεῖται δὲ καὶ τρίπους ἐπίχαλκος, ἐφʼ οὗ πρὶν ἢ τὴν τράπεζαν ποιηθῆναι προετίθεντο τοῖς νικῶσιν οἱ στέφανοι.
Of votive offerings placed within or in the fore-temple, there is the throne of Arimnestus, king among the Tyrrhenians, who was the first barbarian to dedicate an offering to Zeus at Olympia. There are also the bronze horses of Cynisca, commemorative monuments of her Olympic victory. These are smaller than life-size horses, and stand in the fore-temple, on the right as one enters. There is also a bronze-coated tripod, upon which it was customary in earlier times to set out the crowns for victors, before the table was made.
