António Vieira (born February 6, 1608,Lisbon, Portugal—died July 18, 1697,Salvador, Brazil) was aJesuit missionary, orator, diplomat, and master of classical Portugueseprose who played an active role in both Portuguese and Brazilian history. His sermons, letters, and state papers provide a valuable index to the climate of opinion of the 17th-century world.

Vieira went toBrazil with his parents as a child of six. Educated at the Jesuits’ college inBahia, he joined the Society of Jesus in 1623 and was ordained in 1635. He soon became the most popular and influential preacher in the colony, and his sermons exhorting the various races to join the Portuguese in arms against the Dutch invaders of Brazil (1630–54) are considered the first expression of the Brazilian national mystique of forming a new race of mixed bloods. In addition to theTupí-Guaraní tongue, thelingua franca of the Brazilian littoral, Vieira learned a number of local Amazondialects and the Kimbundulanguage of the black slaves who had been brought to Brazil from Angola.

Vieira worked among the Indians and black slaves until 1641, when he went with a mission toPortugal to congratulate KingJohn IV on his accession. The king soon fell under the spell of Vieira’s self-assured and magnetic personality and came to regard the tall, lean,dynamic Jesuit as “the greatestman in the world.” The king made him tutor to the infante, court preacher, and a member of theroyal council. Vieira’s devotion to the king was such that after John’s death (1656) he formed a fixed idea that the king would return to inaugurate a prophesied golden age of peace and prosperity.

Between 1646 and 1650 Vieira was engaged in diplomatic missions to Holland, France, and Italy. But by his outspokenadvocacy fortoleration for Jewish converts toChristianity in Portugal and because of his willingness to cedePernambuco to the Dutch as the price of peace, he made enemies in Portugal. By 1652 it had become prudent for him to leave the country for Brazil. His denunciation of slave-owning there resulted in his return to Lisbon in 1654. During his stay in Portugal, he secured decrees protecting the Brazilian Indians from enslavement and creating a monopoly for the Jesuits in the government of the Indians, and he returned triumphantly in 1655. He resumed his apostolic mission inMaranhão and on the Amazondelta, where for six years he traveled widely and laboured energetically before being forced back to Lisbon in 1661. For prophesying the return of John he was condemned by the Inquisition and imprisoned (1665–67).

On his release (1668) he went to Rome, where he succeeded in securing at least temporary toleration for the converted Jews. He remained there for six years, becoming confessor to Queen Christina of Sweden and a member of her literary academy. In 1681 he returned to Bahia, where he remained, a fighter for the freedom of the Indians, until his death at 89.

Vieira is claimed as a literary master by both the Portuguese and the Brazilians. Though his prose style, in its ornateness, Latinisms, and elaborate conceits, is a product of the Old World, his works are of the New World in their emotional freedom, boldness of thought, and advancedattitude of racial tolerance.
