Diogo Ribeiro

Diogo Ribeiro, also known as Diego Ribero, was a Portuguese cartographer and explorer who worked most of his life in Spain. He worked on the official maps of the Padrón Real (or Padrón General ) from 1518-1532. He also made navigation instruments, including astrolabes and quadrants.

Born as Diogo Ribeiro, he was the son of Afonso Ribeiro and Beatriz de Oliveira. However, there is no known record of the date and place of his birth. He is believed to have become a seaman at an early age and made several voyages to India as a ship pilot. Reportedly, Ribeiro sailed with Pedro Afonso de Aguiar who served as captain in the Armadas of the explorers Vasco da Gama (1502), Lopo Soares (1504), and Afonso de Albuquerque (1509).

By 1516 Diogo Ribeiro and other several Portuguese navigators and cartographers, conflicting with King Manuel I of Portugal, gathered in Seville to serve the newly crowned Charles V. Among them were explorers and cartographers Diogo and Duarte Barbosa, Estêvão Gomes, João Serrão, Ferdinand Magellan and Jorge Reinel, cosmographers Francisco and Ruy Faleiro and the Flemish merchant Christopher de Haro. Ribeiro started working for Charles I (and V of the Holy Roman Empire) in 1518, as a cartographer at the Casa de Contratación in Seville. Ferdinand Magellan took part in the development of the maps used in the first circumnavigation of the Earth.
