[3] Educated by Fray Diego de Landa, from whom he learned the Castilian grammar that he mastered with such perfection that he was named by the Spanish as head of the grammar chair in the chapel of Tizimín, a town in the north of Yucatán where he lived.
With this knowledge he was a valuable help to the Franciscan friars who were in charge of the evangelization of the Yucatán Peninsula and for this purpose he had access - normally denied to native people - to the library of the Convent of San Francisco de Mérida.
He served as general attorney for the Mayan people, intervening in their disputes and defending them in litigation.
