††††The trireme was an ancient warship, so named because it had three rows of oars ('tri' is the Greek word for 'three').
Sea power was important to all the early empires for both trade and conquering new lands. The Greek sea power was based on the trireme. On the front of the ship, under the water line, was a ram used to hole and sink enemy ships. This is a bireme, which had two rows of oars.
