As mentioned earlier, the first documents that were produced were by Jesuit missionaries in the 16th and 17th centuries, such as "Arte da Grammatica da Lingoa mais usada na costa do Brasil" by Father José de Anchieta (1595) and "Arte da Língua Brasilíca" by Luis Figueira (1621). These were detailed grammars that served their religious purposes. Multiple dictionaries have also been written over the years (Mello 1967, Grenand and Epaminondas 1989, Barbosa 1951). More recently, Stradelli (2014) also published a Portuguese-Nheengatu dictionary.
