At the northwest corner of the Italian peninsula the coast-line, as it approaches the French border, bends around to the west in such a way as to form a kind of rounded angle, which, according to the fertile fancy of the Greeks, resembles the human knee. It was probably in recognition of this geographical peculiarity that the hamlet established at this point received some centuries before the Christian era the name which has since been evolved into Genoa. The situation is not only one of the most picturesque in Europe, but it is peculiarly adapted to the development of a small maritime city. For many miles it is the only point at which Nature has afforded a good opportunity for a harbor. Its geographical relations with the region of the Alps and the plains of northern Italy seem to have designated it as the natural point where a common desire for gain should bring into profitable relations the trading propensities of the people along the shores of the Mediterranean. During nearly two thousand years the situation was made all the more favourable by the ease with which it might be defended; for the range of mountains, which encircles it at a distance of only a few miles, made it easy for the inhabitants to protect themselves against the assaults of their enemies. The favouring conditions thus afforded gave to Genoa early in the Christian era a commercial prestige of some importance. The turbulence of the Middle Ages made rapidity of growth quite impossible; but in the time of the Crusades this picturesque city received a large share of that impulse which gave so much life to Venice and the other maritime towns of Italy. Like other cities of its kind, it was filled with seafaring men. It is easy to believe that the boys who grew up in Genoa during the centuries of the Crusades and immediately after, had their imaginations and memories filled to overflowing with accounts of such wonderful adventures as those which, about that time, found expression in the writings of Marco Polo and John de Mandeville. The tales of seafaring adventurers always have a wonderful attraction for boys; and we can well imagine that the yarns spun by the returning sailors of the fourteenth and fifteenth centuries had an altogether peculiar and exceptional fascination...
