Length of a degree.

The calculation of course depended on what was the length of a degree, and on this point there was some difference of opinion. Toscanelli had so reduced a degree's length that China was brought forward on his planisphere till its coast line cut the meridian of the present Newfoundland.

Quinsay.

We can well imagine how this undue contraction of the size of the globe, as the belief lay in the mind of Columbus, and as he expressed it later (July 7, 1503), did much to push him forward, and was a helpful illusion in inducing others to venture upon the voyage with him. The courage required to sail out of some Iberian port due west a hundred and twenty degrees in order to strike the regions about the great Chinese city of Quinsay, or Kanfu, Hangtscheufu, and Kingszu, as it has been later called, was more easily summoned than if the actual distance of two hundred and thirty-one degrees had been recognized, or even the two hundred and four degrees necessary in reality to reach Cipango, or Japan. The views of Toscanelli, as we have seen, reduced the duration of risk westward to so small a figure as fifty-two degrees. So it had not been an unusual belief, more or less prominent for many generations, that with a fair wind it required no great run westward to reach Cathay, if one dared to undertake it. If there were no insurmountable obstacles in the Sea of Darkness, it would not be difficult to reach earlier that multitude of islands which was supposed to fringe the coast of China.

Asiatic islands.

Cipango.

Spanish and Portuguese explorations.

It was a common belief, moreover, that somewhere in this void lay the great island of Cipango,—the goal of Columbus's voyage. Sometimes nearer and sometimes farther it lay from the Asiatic coast. Pinzon saw in Rome in 1491 a map which carried it well away from that coast; and if one could find somewhere in the English archives the sea-chart with which Bartholomew Columbus enforced the views of his brother, to gain the support of the English king, it is supposed that it would reveal a somewhat similar location of the coveted island. Here, then, was a space, larger or smaller, as men differently believed, interjacent along this known zone between the ascertained extreme east in Asia and the accepted most distant west at Cape St. Vincent in Spain, as was thought in Strabo's time, or at the Canaries, as was comprehended in the days of Ptolemy. What there was in this unknown space between Spain and Cathay was the problem which balked the philosophers quite as much as that other uncertainty, which concerned what might possibly be found in the southern hemisphere, could one dare to enter the torrid heats of the supposed equatorial ocean, or in the northern wastes, could one venture to sail beyond the Arctic Circle. These curious quests of the inquisitive and learned minds of the early centuries of the Christian era were the prototypes of the actual explorations which it was given in the fifteenth century to the Spaniards and Portuguese respectively to undertake. The commercial rivalry which had in the past kept Genoa and Venice watchful of each other's advantage had by their maritime ventures in the Atlantic passed to these two peninsular nations, and England was not long behind them in starting in her race for maritime supremacy.

Sea of Darkness.

It was in human nature that these unknown regions should become those either of enchantment or dismay, according to personal proclivities. It is not necessary to seek far for any reason for this. An unknown stretch of waters was just the place for the resorts of the Gorgons and to find the Islands of the Blest, and to nurture other creations of the literary and spiritual instincts, seeking to give a habitation to fancies. It is equally in human nature that what the intellect has habilitated in this way the fears, desires, and superstitions of men in due time turn to their own use. It was easy, under the stress of all this complexity of belief and anticipation, for this supposable interjacent oceanic void to teem in men's imaginations with regions of almost every imaginable character; and when, in the days of the Roman republic, the Canaries were reached, there was no doubt but the ancient Islands of the Blest had been found, only in turn to pass out of cognizance, and once more to fall into the abyss of the Unknown.
