问答题5. Ancient Greek historian Herodotus wrote about the Phoenicians in his work The Histories. He claimed that around 600 B.C., they circumnavigated Africa by sailing south from the Red Sea, west around the Cape of Good Hope, and then north alongside the western part of Africa, whereupon they entered the Mediterranean Sea through the Straits of Gibraltar. This journey took approximately three years to accomplish. Ever since Herodotus made his claim, others have been skeptical about it for a number of valid reasons. To begin with, while the Phoenicians constructed good sailing ships, they were coast huggers not intended for rough, open seas. Their sails were square and therefore unable to do much more than catch a direct breeze, so the ships had little ability to tack into contrary winds. This would have been troublesome on the northward journey by Africa's west coast because the wind mostly blows from the north. The Phoenicians also would have been venturing into the unknown since they would have been unfamiliar with the African coast, its currents, the locations of reefs, and the prevailing winds for nearly the entire journey. The chances are that their ships could not have survived those dangers and either attempted the journey but were forced to turn back or sank somewhere along the way. Finally, the weather around the Cape of Good Hope is some of the worst in the world due to the strong winds and high waves. In other areas, the winds can be becalmed for weeks at a time. A recent attempt to recreate the voyage with a replica Phoenician ship proved the danger of the weather. The voyage only succeeded because the ship had satellite navigation aids, up-to-date weather reports, and an engine it used when the wind was not blowing.
