The progress of discovery now recalls us to Spain. About the year 1567, one Alvaro Mendana de Neyra, who had thus far lived in complete obscurity, followed his uncle Don Pedro de Castro to Lima, in Peru, where he had been appointed governor. Mendana, disdaining commerce, and feeling little inclination to lead a monotonous life on shore, after the taste he had had during the passage of a roving existence upon the water, resolved to undertake the discovery of new lands in the name of the King of Spain. His uncle encouraged him in his design and furnished him with the necessary funds. Mendana set sail from Callao on the 11th of January, 1568. He proceeded fourteen hundred and fifty leagues to the west, and discovered a group of islands in about 10° south latitude. One of them, to which he gave the name of Isabella, is distinguished as having been the scene of the first celebration of a Catholic mass in the Pacific Ocean. He sailed round another of the group, St. Christopher, and, after several disastrous encounters with the natives, returned to Callao. This voyage, the most important undertaken by the Spanish since the discovery of America, gave rise to multitudes of fables, with which the historians and chroniclers of Spain filled the minds of the people during the century which followed. The islands discovered by Mendana were represented as enormously rich in gold and the precious metals. The name of Solomon was given to the group,--a name which was thought to be eminently suited to so luxurious an archipelago, having formerly been that of a luxurious prince. As in those days the art of scientific navigation was in its infancy, and as latitude and longitude were not fixed with any great degree of precision, the position of the Solomon Islands was very loosely marked down by Mendana, and the question of their locality became, and for a long time remained, one of the most puzzling questions in geography.
