or NERIENIS, wife of the Roman god Mars. Very little is known about her, and the ancients themselves were doubtful as to the correct form of her name, though Gellius (13.22) prefers Nerio, which is analogous with Anio. The name is said to be of Sabine origin, and to be synonymous with virtus or fortitudo. (Plaut. Truc. 2.6. 24; Martian. Cap. 3; L. Lydus, de Mens. 4.42.)
