Luis de Valdivia, Arte y gramatica general de la lengua que corre en todo el Reyno de Chile (Lima 1606; Seville 1684)

The first printed grammar of Mapudungun, read here in its Seville 1684 reprint. Its preface argues that one language runs four hundred leagues from Coquimbo to Chiloe, that it has almost no irregular verb, and that it exceeds Latin in the abundance of its tenses. Chapter one gives a repeatable articulatory procedure for a sixth vowel Spanish and Latin do not have. The same book is dedicated to a cavalry commander of the war against its speakers.
