Maturino Gilberti, Arte de la lengua de Michuacan (Mexico, 1558)

The grammar of Purepecha printed at Mexico by Juan Pablos in 1558, sixteen years before the better-known Lagunas Arte and surviving in a single incomplete copy that left the country. Its opening warning is that it would be a very great danger to say this language can be written with whatever letters one likes, and it proves the point with minimal pairs. Its closing folios are model sentences for giving orders in the house, so the book states its own use.
