Diego García de Palacio's Instrucción náutica (Mexico, 1587)

A treatise on the use, building and government of ships, printed at Mexico City by Pedro Ocharte in 1587 and written by a judge of the Audiencia who had already tested American timbers, cotton canvas and henequen rigging and directed the building of two galleons of a thousand tons. Its last twenty-eight folios are a nautical vocabulary, and the Real Academia later used the book to authenticate the words of its first dictionary.
