Consort
The consort of Mars was Nerio or Nerine, "Valor." She represents the vital force (vis), power (potentia) and majesty (maiestas) of Mars. Her name was regarded as Sabine in origin and is equivalent to Latin virtus, "manly virtue" (from vir, "man"). In the early 3rd century BC, the comic playwright Plautus has a reference to Mars greeting Nerio, his wife. A source from late antiquity says that Mars and Nerine were celebrated together at a festival held on March 23. In the later Roman Empire, Nerine came to be identified with Minerva.
Nerio probably originates as a divine personification of Mars' power, as such abstractions in Latin are generally feminine. Her name appears with that of Mars in an archaic prayer invoking a series of abstract qualities, each paired with the name of a deity. The influence of Greek mythology and its anthropomorphic gods may have caused Roman writers to treat these pairs as "marriages."
