Sea from the 3rd millennium BC. However, archaeologists believe that the Stone Age colonization of islands in the Mediterranean around 8,000 BC required fairly large, seaworthy vessels that were paddled and possibly even equipped with sails. The first evidence of more complex craft that are considered to prototypes for later galleys comes from Ancient Egypt during the Old Kingdom (c. 2700–2200 BC). Under the rule of pharaoh Pepi I (2332–2283 BC) these vessels were used to transport troops to raid settlements along the Levantine coast and to ship back slaves and timber. During the reign of Hatshepsut (c. 1479–57 BC), Egyptian galleys traded in luxuries on the Red Sea with the enigmatic Land of Punt, as recorded on wall paintings at the Mortuary Temple of Hatshepsut at Deir el-Bahari. Shipbuilders, probably Phoenician, a seafaring people who lived on the southern and eastern coasts of the Mediterranean, were the first to create the two-level galley that would be widely known under its Greek name, diērēs, or bireme. Even though the Phoenicians were among the most important naval civilizations in early classical antiquity, little detailed evidence have been found concerning the types of ships they used. The best depictions found so far have been small, highly stylized images on seals which depict crescent-shape vessels equipped with one mast and banks of oars. Colorful frescoes on the Minoan settlement on Santorini (c. 1600 BC) show more detailed pictures of vessels with ceremonial tents on deck in a procession. Some of these are rowed, but others are paddled with men laboriously bent over the railings. This has been interpreted as a possible ritual reenactment of more ancient types of vessels, alluding to a time before rowing was invented, but little is otherwise known about the use and design of Minoan ships. In the earliest days of the galley, there was no clear distinction between ships of trade and war other than their actual usage. River boats plied the waterways of ancient Egypt during the Old Kingdom (2700–2200 BC) and seagoing galley-like vessels were recorded bringing back luxuries from across the Red Sea in the reign of pharaoh Hatshepsut. Fitting rams to the bows of vessels sometime around the 8th century BC resulted in a distinct split in the design of warships, and set trade vessels apart, at least when it came to use in naval warfare. The Phoenicians used galleys for transports that were
