Mendoza, the new viceroy of New Spain, a man of fine character but utterly without sympathy for Cortes, and who was instrumental in bringing about his downfall, now determined on an expedition of great magnitude: an expedition that should proceed by both land and water to the wonderful Seven Cities of Cibola, believed to be rich beyond computation. The negro Estevan had lately been sent back to the marvelous northland he so glowingly described, guiding Marcos, the Franciscan monk of Savoyard birth, who was to investigate carefully, as far as possible, the glories recounted and speedily report. They were in the north about the same time (summer of 1539) that Ulloa was sailing up the Sea of Cortes. The negro, who had by arrangement proceeded there some days in advance of Marcos, was killed at the first Pueblo village, and Marcos, afraid of his life, and before he had seen anything of the wonderful cities except a frightened glimpse from a distant hill, beat a precipitate retreat to New Galicia, the province just north of New Spain, and of which Francis Vasquez de Coronado had recently been made governor. Here he astonished Coronado with a description of the vast wealth and beauty of the Seven Cities of Cibola, a description that does credit to his powers of imagination. Coronado lost no time in accompanying Marcos to Mexico, where a conference with Mendoza resulted in the promotion of the monk, and the immediate organisation of the great expedition mentioned. Coronado was made general of the land forces, and Hernando de Alarçon was placed in charge of the ships. Having a land march to make Coronado, started in February, 1540, while Alarçon sailed in May. Coronado proceeded to San Miguel de Culiacan, the last settlement toward the north, near the coast, whence he took a direction slightly east of north. The Ancient Ruin on the Cliff.
