As civilization spread around the Mediterranean Sea, Indian Ocean, and China Sea, larger trading ships came into use to carry bulk cargoes such as olive oil from Greece, cedar wood from Lebanon, grain from Egypt, and rice from China. Typical ancient Merchant Ships had keels and were built of planks, but did not have interior framing. They carried a single mast for a mainsail and were steered with a large paddle. Their broad beam allowed for cargoes far beyond those of dugout canoes. Recent underwater discoveries of ancient merchant ships indicate they had good sailing qualities and required only a small crew.
