God of war and guardian of Rome. More prominent in Roman religion than his Greek counterpart Ares, Mars was also a god of agriculture and fertility. Father of Romulus and Remus, legendary founders of Rome.
Mars was the son of Jupiter and Juno. He fathered Romulus and Remus with the Vestal Virgin Rhea Silvia, making him the divine ancestor of the Roman people.
Mars is a war god, and he is also something Ares almost never is: an ancestor. With the Vestal **Rhea Silvia** he fathered Romulus and Remus, which makes him divine grandfather of the Roman people. The Campus Martius, the army's field, carried his name. So did the month of March, when campaigning weather returned and the Salii danced with the sacred shields.
