Luiz Jorge de Barbuda

Luiz Jorge de Barbuda (1564 (?)–1613 (?) ) was a Portuguese cartographer. It is believed that he was the person known under the Latinized name Ludovicus Georgius, the creator of the influential map of China, published by Abraham Ortelius in 1584 in his Theatrum Orbis Terrarum.

During his life the cartographer was known under the Portuguese name Luiz Jorge, or its Hispanicized version Luis Jorge. Later Spanish writers would "disambiguate" his name using the place of his origin, calling him Luis Jorge de la Barbuda.

Even if Szcześniak's identification of Ludovicus Georgius as Luiz Jorge de Barbuda is correct, the birth date given by Szcześniak may not be in agreement with the biographical points given in . According to Maroto and Piñeiro, Luis Jorge was hired by Philip II of Spain in 1582 as the "master of making navigation charts and world maps" (maestro de hacer cartas de marear y cosmographias). until much more precise information from China-based Jesuit became available (Martino Martini, Novus Atlas Sinensis, 1655).
