Passage 3.10.7
τρίτη δὲ ἐκ τῆς ὁδοῦ τῆς εὐθείας ἐκβολὴ κατὰ τὰ δεξιὰ ἐς Καρύας ἄγει καὶ ἐς τὸ ἱερὸν τῆς Ἀρτέμιδος. τὸ γὰρ χωρίον Ἀρτέμιδος καὶ Νυμφῶν ἐστιν αἱ Κάρυαι καὶ ἄγαλμα ἕστηκεν Ἀρτέμιδος ἐν ὑπαίθρῳ Καρυάτιδος· χοροὺς δὲ ἐνταῦθα αἱ Λακεδαιμονίων παρθένοι κατὰ ἔτος ἱστᾶσι καὶ ἐπιχώριος αὐταῖς καθέστηκεν ὄρχησις. ἀναστρέψαντι δὲ καὶ κατὰ τὴν λεωφόρον ἰόντι ἐρείπια Σελλασίας ἐστί· ταύτην, καθὰ καὶ πρότερον ἔγραψα, ἠνδραποδίσαντο Ἀχαιοὶ Λακεδαιμονίους καὶ τὸν βασιλέα Κλεομένην τὸν Λεωνίδου μάχῃ νικήσαντες.
The third branching from the main road on the right leads to Caryae and to the sanctuary of Artemis. For Caryae is sacred to Artemis and to the Nymphs, and there stands in the open air an image of Artemis Caryatis. Here the maidens of the Lacedaemonians annually perform dances, and a traditional dance has become customary among them. Turning back and continuing along the highway, one reaches the ruins of Sellasia. As I have written previously, the Achaeans reduced this town to slavery, having defeated in battle the Lacedaemonians and their king Cleomenes, the son of Leonidas.
