Sahagún's Relación del autor digna de ser notada

The short appendix Bernardino de Sahagún attached to the tenth book of his Historia general, and the closest thing the sixteenth century produced to a defence of indigenous intellectual capacity written by someone who had tested it. He taught the first four years of Latin at Tlatelolco, records that Spaniards and fellow religious laughed at the attempt, sets down what the pupils could do within three years, and lists the objections raised against them once they could do it.
