So extraordinary were the accounts that many of the cities of Spain were depleted of their most energetic men. Every craft that could sail the seas was called into use, and the building of new vessels was hastened to completion in order to provide for the needs of adventurous prospectors and would-be explorers.

The conquest of the Aztec Empire, with its millions of treasure, by Cortez had already proved the valiancy of Spanish cavaliers. To add to this, the conquest of the Incas by Pizarro and his followers was regarded a miracle of divine interposition.

As a result, Spanish galleons laden with treasure from the conquered countries ploughed the seas, and untold wealth poured into private and royal coffers. Spanish ambition and greed for gold knew no bounds. Cunning and cruelty were employed by the Spaniards to secure their ends. No trials, no hardships were too great for them to endure. No perils daunted them. Western South America, ruled by viceroys for nearly three centuries, brought to Spain its greatest wealth. One-fifth of all the wealth and treasure acquired was reserved for the crown.

When Pizarro first visited the interior of Peru he found an empire well advanced in the arts of civilization. Its temples within and without were richly decorated with gold. There were thousands of miles of excellent roads, of which two were used for military purposes. One of these extended along the lowlands; the other traversed the grand plateau. These roads crossed ravines bridged with solid masonry and were pierced by tunnels cut through solid rock. The construction of these great roads was a more wonderful achievement than the building of the Egyptian pyramids.

The government was systematically organized and to a certain extent it was both paternal and communal. Agriculture was skilfully carried on by means of fertilization and irrigation.

The sun was the chief deity and object of worship of its people. Their most beautifully adorned and renowned sanctuary was the Temple of the Sun at Cuzco. Besides this sacred edifice there were several hundred inferior temples and places of worship scattered through the empire, all plentifully ornamented with gold and silver. Every Inca ruler was regarded as a descendant of the sun and therefore a sacred person.

According to the popular belief, gold consisted of tears wept by the sun and was therefore a sacred metal suitable for beautifying the palaces of the Incas and temples of worship. Not only were the edifices themselves richly adorned with this precious metal, but the sacred vessels and many of the articles of furniture were made of the same material. Silver, also, was much used, but was not considered sacred. So great was the amount of the precious metals used that each royal palace and temple was a veritable mine.

From 1520 to 1525 reports of a rich empire at the south were circulated among the adventurers congregated at Panama. At length they were confirmed in a great measure by travellers who had voyaged southward along the coast. Francisco Pizarro, a restless spirit who had been associated with Balboa and others in discovery and exploration, determining to test the truth of these reports, made several voyages south.

Finally, he landed on the shores of Peru with an army of followers who numbered less than two hundred. He met with but little opposition from the natives while marching toward the interior, and although he plundered some of the places through which he passed, the people received him with marks of friendship.

In some instances towns of several thousand population were deserted on the approach of the Spaniards, so great was the terror inspired by the white men, especially by those on horseback. At first it was the policy of the invaders to treat the natives with kindness in order to accomplish their purpose, namely, to conquer the Peruvian Empire in the same manner that Cortez had conquered the Aztecs. They were accompanied by two of the natives who previously had been taken to Spain and taught the Spanish language. By this means the Spaniards were able to communicate with the people.
