A privateer was leaving Genoa on a certain June morning in 1461, and crowds of people had gathered on the quays to see the ship sail. Dark-hued men from the distant shores of Africa, clad in brilliant red and yellow and blue blouses or tunics and hose, with dozens of glittering gilded chains about their necks, and rings in their ears, jostled sun-browned sailors and merchants from the east, and the fairer-skinned men and women of the north. Genoa was a great seaport in those days, one of the greatest ports of the known world, and her fleets sailed forth to trade with Spain and Portugal, France and England, and even with the countries to the north of Europe. The sea had made Genoa rich, had given fortunes to the nobles who lived in the great white marble palaces that shone in the sun, had placed her on an equal footing with that other great Italian sea city, Venice, with whom she was continually at war. But all the ships that left her harbor were not trading vessels. Genoa the Superb had many enemies always on the alert to swoop down upon her trade. So she had to maintain a great war-fleet. In addition to this danger, the Mediterranean was then the home of roving pirates, ready to seize any vessel, without regard to its flag, which promised to yield them booty.
