Passage 3.19.5
πεποίηται δὲ ἐπὶ τοῦ βωμοῦ καὶ Ἡρακλῆς ὑπὸ Ἀθηνᾶς καὶ θεῶν τῶν ἄλλων καὶ οὗτος ἀγόμενος ἐς οὐρανόν. εἰσὶ δὲ καὶ αἱ Θεστίου θυγατέρες ἐπὶ τῷ βωμῷ, καὶ Μοῦσαί τε καὶ Ὧραι. περὶ δὲ ἀνέμου Ζεφύρου, καὶ ὡς ὑπὸ τοῦ Ἀπόλλωνος Ὑάκινθος ἀπέθανεν ἄκοντος, καὶ τὰ ἐς τὸ ἄνθος εἰρημένα τάχα μὲν ἂν ἔχοι καὶ ἄλλως, δοκείτω δὲ ᾗ λέγεται.
On the altar is depicted also Heracles, led by Athena and the other gods, as he too is taken up into heaven. Represented on the altar are likewise the daughters of Thestius, as well as the Muses and the Horae. Concerning the wind Zephyrus, and the accidental death of Hyacinthus by Apollo, and the transformation of the youth into the flower, perhaps one could interpret it otherwise as well; yet let it be as it is traditionally told.
