“Mêdea: Genitals; also, plans.”
Μήδεα: τὸ αἰδοῖον καὶ τὰ βουλεύματα.
Mêdeia: Kolkhian, daughter of Aietes, most talented of women at magic potions. She made Jason unharmed when he yoked the fire-breathing bulls to plow the earth. And after he took the golden fleece, he also took Medeia with him. This is why Greeks call naphtha [flammable oil] Mêdea’s oil.
Μήδεια, Κολχίς, ἡ Αἰήτου θυγάτηρ, φαρμακιστάτη γυναικῶν· ἥτις ἀσινῶς ἐποίησε τὸν ᾿Ιάσονα ζεύξαντα τοὺς πυριπνόους ταύρους ἀρόσαι τὴν γῆν. καὶ λαβὼν τὸ χρυσόμαλλον δέρας ἠγάγετο τὴν Μή-δειαν. ὅτι οἱ ῞Ελληνες τὴν νάφθαν καλοῦσι Μηδείας ἔλαιον.
“Naphtha: this has three forms. Commonly it is called naptha [feminine]. It is also found in the neuter form, though in Plutarch we find the masculine naphthos. The Greeks also call it Mêdeia’s oil, while the Persians call it naphtha.”
Νάφθα: τριγενὲς τοῦτο· κοινῶς μὲν γὰρ ἡ νάφθα, εὕρηται δὲ καὶ οὐδετέρως τὸ νάφθα, παρὰ Πλουτάρχῳ δὲ καὶ ὁ νάφθος. ὅτι οἱ μὲν ῞Ελληνες Μηδείας ἔλαιον ταύτην καλοῦσιν, οἱ δὲ Μῆδοι νάφθαν.
