André Thevet (//; French: [təvɛ]; 1516 – 23 November 1590) was a French Franciscan priest, explorer, cosmographer and writer who travelled to the near East and to south America in the 16th century. His most significant book was The New Found World, or Antarctike which compiled a number of different sources and his own experience into what purported to be a first hand account of his experiences in France Antarctique, a French settlement near modern Rio de Janeiro.
Thevet was born in Angoulême. At ten years of age, he entered the convent of Franciscans of Angoulême. He visited Italy at the same time as Guillaume Rondelet. In 1549, thanks to the support of John, Cardinal of Lorraine, he embarked on an extended exploration trip to Asia, Greece, Rhodes, Palestine and Egypt. He accompanied the French ambassador Gabriel de Luetz to Istanbul.
Almost immediately after this, he set sail again as the chaplain of the fleet of Nicolas Durand de Villegaignon intended to establish a French colony near what is now Rio de Janeiro. Thevet arrived there on 10 Nov 1555 but only stayed in the colony for about 10 weeks before returning to France. He was made an almoner to Catherine de Médici and later was employed by the king.
Thevet died in Paris on 23 November 1590.
On return from the Americas, Thevet in 1557 or 1558 published a book, Les singularitez de la France Antarctique. Although purportedly based on his first hand experiences, Thevet also used previous published sources, but also verbal accounts from other explorers and sailors, and from indigenous Canadians who had been brought back to France. Thevet later settled a court case with another scholar who claimed to have been responsible for the actual writing. An edition of Les singularitez de la France Antarctique was printed in Antwerp by Plantin in 1558 and an English edition, The New Found World, or Antarctike, was printed in 1568.
Thevet's use of such a variety of sources not otherwise printed, despite the considerable errors and contradictions, means that his work remains valuable for the ethnography of both eastern Canada and Brazil. Les singularitez de la France Antarctique contains the first descriptions in European texts of plants such as the manioc, pineapples, peanuts and tobacco, as well as of the animals macaw, sloth and tapir. The text includes an account of cannibalism that was one of the influences on Montaigne's essay on cannibalism.
Once Thevet was established as cosmographer to the French court he compiled his Cosmographie Universelle, intended to describe every part of the known world. A dispute arose with a collaborator, François de Belleforest, who left Thevet's employ to publish his own Cosmographie in 1572 before Thevey's work finally appeared in 1575.
In 1584 Thevet published a collection of biographies, Vrais pourtraits et vies des homes illustres, which was critical of Protestants. He left two unpublished manuscripts. One was an almanac of islands, Grand Insulaire, and the other, Histoire de deux voyages was an account of his travels.
