Ludovico Bertonio, Vocabulario dela lengua Aymara (Juli, 1612)

The great dictionary of Aymara, printed at the Jesuit press of Juli on Lake Titicaca, corrected on the order of an oidor of the Audiencia of Lima and priced by the crown at a real the sheet. Its prologue argues that Aymara is grammatically simpler than Latin, Italian or Spanish, counts barely twenty priests who know it against more than a thousand Aymara towns, and tells its readers that if the Indians profit little from Christian teaching the fault is not wholly theirs.
