== Early == The first known was given by Julius Caesar in Rome in 46 BC on occasion of his quadruple triumph. After having a basin dug near the Tiber, capable of holding actual biremes, triremes and quinqueremes, he made 2,000 combatants and 4,000 rowers, all prisoners of war, fight. In 2 BC for the inauguration of the Temple of Mars Ultor ("Mars the Avenger"), Augustus gave a grander based on Caesar's model. This naumachia depicted a battle between the Greeks and the Persians and required a basin that was 365 by 550 meters, which was created straddling the Tiber. Res Gestæ (§ 23) claimed that 3000 men, not counting rowers, fought in 30 vessels with rams and several smaller boats.
