In Greek mythology, Erato is one of the Greek Muses, the inspirational goddesses of literature, science, and the arts. 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.

In ancient Greek religion and mythology, the Muses are the inspirational goddesses of literature, science, and the arts. They were considered the source of the knowledge embodied in the poetry, lyric songs, and myths that were related orally for centuries in ancient Greek culture.
