 He took the Franciscan habit, as is generally agreed, in 1579, and pursued a course of studies in Latin, theology, philosophy and Nahuatl.Brief notices in his own works put him at the convent in Tlacopan in 1582 and (while still a youth) at the convent in Chiauhtla - the presumption being that these relate to his novitiate.It is uncertain if he began his studies at the "convento mayor de San Francisco" in Mexico City, but it is presumed that part at least of his studies were conducted while resident at the convent of Santiago, Tlatelolco.
