Bellona in Greek and Roman mythology, was the sister of Mars, or his nurse, or his wife, or daughter, the goddess of war. When Mars went to the battle-field, she prepared for him his wagon and his horses. Her temple in Rome was greatly celebrated; the senate assembled in it when transactions were carried on with ambassadors of an enemy. The priests of this goddess were foreigners. At their festivals they cut themselves with knives. The common people held them as holy men. Bellona had two-other temples in the cities Comana in Pontus and in Cappadocia.
