Roman galleys were ancient ships used by the Roman Empire primarily for naval warfare and trade. These vessels were typically long and narrow, designed for speed and maneuverability. They were powered by both sails and oars, allowing them to navigate various water conditions effectively. The most common type of galley was the trireme, which featured three rows of oars on each side. Galleys played a crucial role in Roman naval battles, enabling the empire to project its power across the Mediterranean Sea. Their design allowed for quick attacks and retreats, making them essential for both military and commercial purposes during the height of Roman influence.
