“ FESTUS, SEXTUS POMPEIUS, Roman grammarian, probably flourished in the 2nd century A.D. He made an epitome of the celebrated work De verborum significatu, a valuable treatise alphabetically arranged, written by M. Verrius Flaccus, a freedman and celebrated grammarian who flourished in the reign of Augustus. Festus gives the etymology as well as the meaning of every word; and his work throws considerable light on the language, mythology and antiquities of ancient Rome. ”
