Erato (dryad) In Greek mythology, Erato ( ; Ancient Greek: Ἐρατώ "desired" or "lovely") was a dryad. She was the priestess and prophetess of the god Pan, verses were attributed to her at an ancient oracle of the god, located at Megalopolis near Acacesium. Erato was married to Arcas, the son of Zeus and Callisto, and bore him three sons, Azan, Apheidas, and Elatus.
Euterpe In Greek mythology, Euterpe ( ; Greek: Eὐτέρπη , ] , ] ; "rejoicing well" or "delight" from Ancient Greek εὖ 'well' + τέρπειν "terpein" 'to please') was one of the Muses, the daughters of Mnemosyne, fathered by Zeus. Called the "Giver of delight", when later poets assigned roles to each of the Muses, she was the muse of music. In late Classical times she was named muse of lyric poetry and depicted holding a flute. A few say she invented the "aulos" or double-flute, though most mythographers credit Marsyas with its invention.
