Aesop, Fable 50:
A weasel, smitten by desire for a beautiful young man, prayed to Aphrodite and asked to be transformed into a woman. The goddess took pity on her and changed her into a beautiful maiden. When the young man saw her, he was seized with desire and brought her home. When they took their places in the bedroom, Aphrodite wondered wither the weasel, having changed its form, had also changed its way of life. So, she set a mouse between the lovers. The girl, forgetting everything present, stood up from the bed and chased after the mouse with the aim of eating it. The goddess was irritated by this, so she caused the girl to revert to her old form as a weasel.
γαλῆ ἐρασθεῖσα νεανίσκου εὐπρεποῦς ηὔξατο τῇ ᾿Αφροδίτῃ, ὅπως αὐτὴν μεταμορφώσῃ εἰς γυναῖκα. καὶ ἡ θεὸς ἐλεήσασα αὐτῆς τὸ πάθος μετετύπωσεν αὐτὴν εἰς κόρην εὐειδῆ. καὶ οὕτως ὁ νεανίσκος θεασάμενος αὐτὴν καὶ ἐρασθεὶς οἴκαδε ὡς ἑαυτὸν ἀπήγαγε. καθημένων δ’ αὐτῶν ἐν τῷ θαλάμῳ ἡ ᾿Αφροδίτη γνῶναι βουλομένη, εἰ μεταβαλοῦσα τὸ σῶμα ἡ γαλῆ καὶ τὸν τρόπον ἤλλαξε, μῦν εἰς τὸ μέσονκαθῆκεν. ἡ δὲ ἐπιλαθομένη τῶν παρόντων ἐξαναστᾶσα ἀπὸ τῆς κοίτης τὸν μῦν ἐδίωκε καταφαγεῖν ἐθέλουσα. καὶ ἡ θεὸς ἀγανακτήσασα κατ’ αὐτῆς πάλιν αὐτὴν εἰς τὴν ἀρχαίαν φύσιν ἀποκατέστησεν.
