ODE'UM (ᾠδεῖον). The Odeum; a small theatre with a convex roof, built by Pericles at Athens for musical performances (ᾠδαί. Plutarch, Pericl. 13. Vitruv. v. 9, 10.). Hence the name was adopted for any small theatre covered with a roof (theatrum tectum), and appropriated as a concert room. Suet. Dom. 5.
