page 141 Pedro Cieza de León, La Chronica del Peru (The Chronicle of Peru), (Antwerp, (Belgium): Martin Nucio, 1554), p. 141. Note: Cieza discussed the Nazca region of Peru and said that "y por algunas partes delos arenales se veen señales, paraque atinen el camino que han de lleuar" ("and in some parts of the desert are seen signals, so that they [i.e., the Indians] find the path that has to be taken").
Luis Monzón (1586) "Descripcion de la tierra del repartimiento de los rucanas antamarcas de la corona real, jurisdicion de la ciudad de Guamanga. año de 1586." in: Marcos Jiménez de la Espada, ed., Relaciones geográficas de Indias: Peru, volume 1 (Madrid, Spain: Manuel G. Hernandez, 1881), pp. 197–216. On page 210, Munzón notes seeing ancient ruins, saying "y hay señales de calles" ("and there are signs of streets"). Munzón asked elderly Indians about the ruins. They told him that before the Inca, a people whom "llamaron viracochas" ("they called viracochas") inhabited the area, and "A éstos les hacian caminos, que hoy dia son vistos, tan anchos como una calle" ("To those [places] they made paths, that are seen today, as wide as a street").
