Stone Inscription, thought by some to be a forgery from the 1930s, very often (and perhaps wrongly) attributed to Fray Marcos de Niza, located in Pima Canyon near Phoenix, Arizona South Mountain Park.
He went to America in 1531, and after serving his order zealously in Peru, Guatemala and was chosen to explore the country north of Sonora, whose wealth was pictured in the hearsay stories of Álvar Núñez Cabeza de Vaca. In 1537 he be established in Mexico City. Preceded by Estevanico, the Moorish companion of Cabeza de Vaca in his wanderings and the Black Mexican of Zuni traditions, Fray Marcos left Culiacán in March 1539, crossed south-eastern Arizona, penetrated to the Zuni or the Seven Cities of Cibola, and in September returned to Culiacán. He saw Cibola only from a distance, and his description of it as equal in size to Mexico City was probably exact; but he embodied much mere hearsay in his report, Descubrimiento de las siete ciudades, which led Francisco Vázquez de Coronado to make his famous expedition next year to Zuni Pueblo, in present-day New Mexico, of which Fray Marcos was the guide; and the realities proved a great disappointment.
Fray Marcos was made provincial superior of his order for Mexico before the second trip to Zuni, and returned in 1541 to the capital, in shame, where for a time was able to exercise the highest office of the Franciscans, in the province. He died there in March, 1558.
