In the fifteenth century, a Portuguese prince known as Henry the Navigator was determined to find a sea route to Ethiopia, from where he hoped to launch a crusade against the non-Christian world.Dismissing popular superstitions about giant sea serpents waiting to ensnare ships, Henry began, in 1424, to order his ships to sail down the western shore of Africa and round the bottom of Africa.Over the next ten years, fifteen different ships' crews would head south, take one look at the turbulent tides of Africa's cape, and turn back.The sailors believed that they were at the edge of the "Sea of Darkness," the most fearsome place on Earth, home to a watery cave filled with huge snakes that would swallow their ship.In 1434, Henry ordered explorer Gil Eannes to "strain every nerve to pass that cape." Despite mariners' fear that they might sail off the edge of the world, Eannes stayed farther out in the ocean as he rounded the cape.When he returned home that same year and described his calm and uneventful voyage, people began to realize that their fears were unfounded.Thanks to Prince Henry and explorer Gill Eannes, the Age of Discovery was unofficially launched.
