Fernão de Oliveira

An adventurous humanist and renaissance man, he studied and published the first grammar of the Portuguese language, the Grammatica da lingoagem portuguesa, in 1536.

Starting in 1520, he studied at the Dominican Convent of Évora, where he was a disciple of André de Resende,[1][3] but later left for Spain.

[4][5] He had a troubled adventurous life, engaging in secret religious missions in Italy, perhaps for king John III of Portugal.

Having returned to Portugal in 1547, he was arrested by the Portuguese Inquisition due to his religious opinions; he was freed in 1551, through the intervention of Cardinal Henrique.

He joined in an expedition organized by king John III in North Africa, where he was made prisoner for a year.
