“Cowherds: Menekrates the Xanthian reports in his Lykian Matters and Nicander does as well. Once she gave birth to Apollo and Artemis on the island Asteria, Leto went to Lykia carrying the children to the baths of Xanthus. And as soon she she appeared in the land, she went to the Melitean spring where she wanted her children to drink before they went to the Xanthus.
But when some cowherds drove her away, so that their cattle might drink from the spring, Leto retreated, abandoning the Melitê, and wolves came to meet her, and they gave her directions and led her right up to the Xanthus itself while wagging their tails. She drank the water, bathed her children and made the Xanthus sacred to Apollo. She also changed the land’s name to Lykia—it was called Tremilis before—after the wolves who led her there.
Then she went again to the spring to bring punishment to the cowherds who drove her off. At they time they were washing their cattle near the spring. After she changed them all into frogs and struck their backs and shoulders with rough stones, she threw them all into the spring and granted them life in the water. In our time still, they shout out along the rivers and ponds.”
Βουκόλοι. ἱστορεῖ Μενεκράτης Ξάνθιος Λυκιακοῖς καὶ Νίκανδρος. Λητὼ ἐπεὶ ἔτεκεν ᾽Απόλλωνα καὶ ῎Αρτεμιν ἐν ᾽Αστερίαι τῆι νήσωι, ἀφίκετο εἰς Λυκίαν ἐπιφερομένη τοὺς παῖδας ἐπὶ τὰ λουτρὰ τοῦ Ξάνθου καὶ ἐπεὶ τάχιστα ἐγένετο ἐν τῆι γῆι ταύτηι, ἐνέτυχε πρῶτα Μελίτηι κρήνηι, καὶ προεθυμεῖτο πρὶν ἐπὶ τὸν Ξάνθον ἐλθεῖν ἐνταυθοῖ τοὺς παῖδας ἀπολοῦσαι. (2) ἐπεὶ δὲ αὐτὴν ἐξήλασαν ἄνδρες βουκόλοι, ὅπως ἂν αὐτοῖς οἱ βόες ἐκ τῆς κρήνης πίωσιν, ἀπαλλάττεται καταλιποῦσα τὴν Μελίτην ἡ Λητώ, λύκοι δὲ συναντόμενοι καὶ σήναντες ὑφηγήσαντο τῆς ὁδοῦ, καὶ ἀπήγαγον ἄχρι πρὸς τὸν ποταμὸν αὐτὴν τὸν Ξάνθον. (3) ἡ δὲ πιοῦσα τοῦ ὕδατος καὶ ἀπολούσασα τοὺς παῖδας τὸν μὲν Ξάνθον ἱερὸν ἀπέδειξεν ᾽Απόλλωνος, τὴν δὲ γῆν Τρεμιλίδα λεγομένην Λυκίαν μετωνόμασεν ἀπὸ τῶν καθηγησαμένων λύκων. (4) ἐπὶ δὲ τὴν κρήνην αὖτις ἐξίκετο δίκην ἐπιβαλοῦσα τοῖς ἀπελάσασιν αὐτὴν βουκόλοις. καὶ οἱ μὲν ἀπέλουον τότε παρὰ τὴν κρήνην τοὺς βοῦς, Λητὼ δὲ μεταβαλοῦσα πάντας ἐποίησε βατράχους, καὶ λίθωι τραχεῖ τύπτουσα τὰ νῶτα καὶ τοὺς ὤμους κατέβαλε πάντας εἰς τὴν κρήνην, καὶ βίον ἔδωκεν αὐτοῖς καθ᾽ ὓδατος · οἱ δὲ ἄχρι νῦν παρὰ ποταμοὺς βοῶσι καὶ λίμνας.
