Ogier Ghislain De Busbecq [Augerius Gislenius] (1522-1592), Flemish writer and traveller, was born at Comines, and educated at the university of Louvain and elsewhere. Having served the emperor Charles V. and his son, Philip II. of Spain, he entered the service of the emperor Ferdinand I., who sent him as ambassador to the sultan Suleiman I. the Magnificent. He returned to Vienna in 1562 to become tutor to the sons of Maximilian II., afterwards emperor, subsequently taking the position of master of the household of Elizabeth, widow of Charles IX., king of France, and daughter of Maximilian. Busbecq was an excellent scholar, a graceful writer and a clever diplomatist. He collected valuable manuscripts, rare coins and curious inscriptions, and introduced various plants into Germany. He died at the castle of Maillot near Rouen on the 28th of October 1592. Busbecq wrote Itinera Constantinopolitanum et Amasianum (Antwerp, 1581), a work showing considerable insight into Turkish politics. This was published in Paris in 1589 as A.G. Busbequii legationis Turcicae epistolae iv., and has been translated into several languages. He was a frequent visitor to France, and wrote Epistolae ad Rudolphum II. Imperatorem e Gallia scriptae (Louvain, 1630), an interesting account of affairs at the French court.
