In Greek mythology, Erato (/ˈɛrətoʊ/; Ancient Greek: Ἐρατώ) is one of the Muses, associated with erotic lyric poetry. The name would mean "desired" or "lovely", if derived from the same root as Eros, as Apollonius of Rhodes playfully suggested in the invocation to Erato that begins Book III of his Argonautica.
