Shortly after George of Speyer, and entirely unconnected with him, Francisco Pizarro, the conqueror of Peru, had given an impulse to the exploration of the Amazon from the Pacific side of the continent. In 1538, distrusting Belalcazar, he sent his brother, Gonzalo Pizarro, to Quito to supersede his suspected lieutenant. The following year Gonzalo heard that the cinnamon-tree abounded in the forests on the eastern slope of the Andes, and that farther east dwelt powerful Indian tribes rich in gold. That is, while the original and genuine myth of the Dorado had reached to Quito from the north, the echo myth of Meta had got there from the east. Since Belalcazar had gone to the real former home of the Dorado, and had failed to find that gentleman at home, it was supposed that the home must be somewhere else,--east, instead of north, from Quito. Gonzalo made his disastrous expedition into the eastern forests with two hundred and twenty men. In the two years of that ghastly journey all the horses perished, and so did all the Indian companions; and the few Spaniards who survived to get back to Peru in 1541 were utterly broken down. The cinnamon-tree had been found, but not the Gilded Man. One of Gonzalo's lieutenants, Francisco de Orellana, had gone in advance on the upper Amazon with fifty men in a crazy boat. The two companies were unable to come together again, and Orellana finally drifted down the Amazon to its mouth with untold sufferings. Floating out into the Atlantic, they finally reached the island of Cubagua, Sept. 11, 1541. This expedition was the first to bring the world reliable information as to the size and nature of the greatest river on earth, and also to give that river the name it bears to-day. They encountered Indian tribes whose women fought side by side with the men, and for that reason named it _Rio de las Amazones_,--River of the Amazons. In 1543 Hernan Perez Quesada, a brother of the conqueror, penetrated the regions which George of Speyer had visited. He went in from Bogota, having heard the twisted myth of Meta, but only found misery, hunger, disease, and hostile savages in the sixteen awful months he floundered in the wilderness.
