Passage 8.9.3
Πραξιτέλης δὲ τὰ ἀγάλματα αὐτήν τε καθημένην ἐν θρόνῳ καὶ παρεστώσας ἐποίησεν Ἀθηνᾶν καὶ Ἥβην παῖδα Ἥρας. πρὸς δὲ τῆς Ἥρας τῷ βωμῷ καὶ Ἀρκάδος τάφος τοῦ Καλλιστοῦς ἐστι· τὰ δὲ ὀστᾶ τοῦ Ἀρκάδος ἐπηγάγοντο ἐκ Μαινάλου, χρησμοῦ σφισιν ἐλθόντος ἐκ Δελφῶν·
Praxiteles fashioned the statues—Hera herself seated on a throne and standing beside her Athena and Hebe, daughter of Hera. Near the altar of Hera is also the tomb of Arcas, son of Callisto. The bones of Arcas were brought there from Mount Maenalus, in accordance with an oracle delivered to them from Delphi.
