The prologue to Fray Juan Bautista's Sermonario (Mexico, 1606)

A Franciscan who had not wanted to learn Nahuatl, and who published eleven books in it, opened his last big one by naming the eight Nahua scholars who had made them: where each was born, what he could do, when he died, and which famous friar's dictionary he had actually helped compose. It is the fullest attribution of indigenous authorship printed in sixteenth-century New Spain, and it survives because a nineteenth-century bibliographer copied it out of a book already almost impossible to find.
