What is "flamen martialis"

Flamen \Fla"men\, n.; pl. E. Flammens, L. Flamines. [L.] (Rom. Antiq.) A priest devoted to the service of a particular god, from whom he received a distinguishing epithet. The most honored were those of Jupiter, Mars, and Quirinus, called respectively Flamen Dialis, Flamen Martialis, and Flamen Quirinalis.

Affrights the flamens at their service quaint.
--Milton.

In ancient Roman religion, the Flamen Martialis was the high priest of the official state cult of Mars, the god of war. He was one of the flamines maiores, the three high priests who were the most important of the fifteen flamens. The Flamen Martialis would have led public rites on the days sacred to Mars. Among his duties was the ritual brandishing of the sacred spears of Mars when the Roman army was preparing for war.

Like other flamines maiores, the high priest of Mars was a patrician and required to marry through the ceremony of confarreatio. It is not clear whether the death of his wife required him to resign his duties, as was the case for the Flamen Dialis.
