Pareja's Arte de la lengua timuquana (Mexico, 1614)

The grammar of Timucua, a language of the Florida peninsula, written by the Franciscan Francisco Pareja and printed at Mexico by Juan Ruyz in 1614. It is the earliest printed grammar of any language of what is now the United States, and for a language with no living speakers it is the principal record that exists. Its own title page hints that an earlier edition has been lost; its editors state that within a century of its printing the people who spoke the language had all but disappeared.
