a Roman divinity of the art of healing, ini whose honour the festival of the Meditrinalia was celebrated in the month of October. (Varro, Dc L. L.6.21; Paul Diac. p. 123, ed. Müller.) Varro connects the name with the verb mederi, to heal, and this seems to accord well with the rites observed at the festival of the goddess. (Dict. of Ant. s. v. Meditrinalia.)
