Worldmap by Diogo Ribeiro, 1529

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.[1]

Early life[edit]

Born as Diogo Ribeiro, he was the son of Afonso Ribeiro and Beatriz de Oliveira.[1] 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).[1]

Ribeiro started working for Charles V in 1518,[2] as a cartographer at the Casa de Contratación in Seville. He adopted Spanish citizenship in 1519, and took part in the development of the maps used in the first circumnavigation of the Earth.

On January 10, 1523, he was named Royal Cosmographer and "master in the art of creating maps, astrolabes, and other instruments". He eventually succeeded Sebastian Cabot (who left on a voyage) as the head cartographer. Cabot published his first map in 1544.

In 1524, Ribeiro participated in the Spanish delegation at the Conference of Badajoz, where Spain and Portugal discussed whether the Philippines were on the Spanish or Portuguese side of the Treaty of Tordesillas.

In 1527, Ribeiro finished the Padrón Real, the official (and secret) Spanish map used as template for the maps present in all Spanish ships. It is considered the first scientific world map.

In 1531, he invented a bronze water pump that was able to pump water out ten times faster than the previous models.

Diogo Ribeiro died in 1533.

First scientific world map[edit]

Ribeiro's most important work is the 1527 Padrón Real. There are 6 copies attributed to Ribeiro,[3] including at the Weimar Grand Ducal Library (1527 Mundus Novus) and at the Vatican Library, in Vatican City (1529 Propaganda Map or Carta Universal).[3] The layout of the map (Mapamundi) is strongly influenced by the information obtained during the Magellan-Elcano trip around the world.

Diogo's map delineates very precisely the coasts of Central and South America. It shows the whole east coast of the Americas but of the west coast only the area from Guatemala to Ecuador. However, neither Australia nor Antarctica appear, and the Indian subcontinent appears too small. The map shows, for the first time, the real extension of the Pacific Ocean. It also shows, for the first time, the North American coast as a continuous one (probably influenced by Estêvão Gomes's exploration in 1524/25). It also shows the demarcation of the Treaty of Tordesillas. The absence of any large continent south of Asia is evidence that there had been no discovery of Australia at that date.
