BARROS, JOO DE

born c. 1496, , Viseu?, Port. died Oct. 20, 1570, Ribeira de Litm, near Pombal Portuguese historian and civil servant who wrote Dcadas da sia, 4 vol. (15521615), one of the first great accounts of European overseas exploration and colonization. Barros was educated in the household of the Portuguese heir-apparent and became a good classical scholar. His chivalrous romance Crnica do Imperador Clarimundo (1520) induced King Manuel I of Portugal to encourage Barros in his idea of writing an epic history of the Portuguese in Asia. But first he wrote several moral, pedagogical, and grammatical works, including an elementary Portuguese primer-catechism (1539) that became the prototype of all such works. In 1522 the succeeding king, John III, sent Barros to Guinea (in western Africa), and soon after his return he was appointed treasurer (152528) and then factor of the Casa da India e Mina (153367), a post corresponding to crown administrator of the Portuguese colonies in Guinea and India. It was in this period that Barros wrote Dcadas da sia, an epic historical account of Portuguese discoveries and conquests in the Orient to 1538. In compiling his chronicle, Barros used his official position to consult returned soldiers, merchants, and administrators and peruse all the official correspondence, while he himself was personally involved in the dispatch and return of the annual India fleets. He finished the first draft in 1539; the first volume was published in 1552, with subsequent volumes appearing in 1553 and 1563. The last volume, which appeared posthumously in 1615, covered the period from 1539 to the end of the century and was edited and written by Diogo do Couto. Barros' other works on geography, commerce, and navigation disappeared after his death.
