MARCO POLO
Of course, there was always the possibility of making the voyage by sea. But the sea was very unpopular in the Middle Ages and for many very good reasons. In the first place, ships were very small. The vessels on which Magellan made his famous trip around the world, which lasted many years, were not as large as a modern ferryboat. They carried from twenty to fifty men, who lived in dingy quarters (too low to allow any of them to stand up straight) and the sailors were obliged to eat poorly cooked food as the kitchen arrangements were very bad and no fire could be made whenever the weather was the least bit rough. The mediaeval world knew how to pickle herring and how to dry fish. But there were no canned goods and fresh vegetables were never seen on the bill of fare as soon as the coast had been left behind. Water was carried in small barrels. It soon became stale and then tasted of rotten wood and iron rust and was full of slimy growing things. As the people of the Middle Ages knew nothing about microbes (Roger Bacon, the learned monk of the thirteenth century seems to have suspected their existence, but he wisely kept his discovery to himself) they often drank unclean water and sometimes the whole crew died of typhoid fever. Indeed the mortality on board the ships of the earliest navigators was terrible. Of the two hundred sailors who in the year 1519 left Seville to accompany Magellan on his famous voyage around the world, only eighteen returned. As late as the seventeenth century when there was a brisk trade between western Europe and the Indies, a mortality of 40 percent was nothing unusual for a trip from Amsterdam to Batavia and back. The greater part of these victims died of scurvy, a disease which is caused by lack of fresh vegetables and which affects the gums and poisons the blood until the patient dies of sheer exhaustion.
