Antonio Machoni, Arte y vocabulario de la lengua lule y tonocoté (Madrid, 1732)

The only printed grammar and dictionary of Lule and Tonocoté, two Chaco languages that no longer have speakers. A Sardinian Jesuit working on the Tucumán frontier put the languages into rules and got them through a Madrid press in 1732 — a hundred years after an earlier grammar of the same speech was written and lost for want of a printer. The same preliminaries record why the Lules were exempted from encomienda, what they owed instead, and the epidemic that met the mission on arrival.
