Bellona goddess of war. One of the numinous gods of Rome (without a particular mythology and possibly of Etruscan origin), probably the Romans original war deity, predating Mars. She accompanied Mars into battle and is taken variously as his sister, wife or daughter.
Bellona's attribute is a sword and she is depicted wearing a helmet and armed with a spear and a torch.
Her name derived from the latin bellum (War), meaning War-waging.
