Andrés Pérez de Ribas, Historia de los triumphos de nuestra santa fee (Madrid, 1645)

The first sustained printed account of the peoples of Sinaloa, Sonora and the sierra of Durango, published at Madrid in 1645 by a Jesuit who had spent sixteen years among them and says so on the page. Its title page also advertises armed victories, and its censor states that the book will justify the crown's right of conquest. Its chapter 20 records the author comparing the radical words of their languages with Nahuatl and concluding they had come from the north.
