Cantino planisphere

Cantino planisphere (1502), Biblioteca Estense, Modena, Italy

The Cantino planisphere or Cantino world map is a manuscript Portuguese world map preserved at the Biblioteca Estense in Modena, Italy. It is named after Alberto Cantino, an agent for the Duke of Ferrara, who successfully smuggled it from Portugal to Italy in 1502. It measures 220 x 105 cm.[1]

The planisphere is the earliest surviving map showing Portuguese geographic discoveries in the east and west and is particularly notable for portraying a fragmentary record of the Brazilian coast, which the Portuguese explorer Pedro Álvares Cabral explored in 1500, the southern coast of Greenland, explored in the late 1490s, and the African coast of the Atlantic and Indian Oceans with remarkable accuracy and detail.

It was valuable at the beginning of the sixteenth century because it showed detailed and up-to-date strategic information in a time when geographic knowledge of the world was growing at a fast pace. It is important in the modern era because it contains unique historical information about the maritime exploration and the evolution of nautical cartography during the Age of Discovery. The Cantino planisphere is the earliest extant nautical chart that depicts places in Africa and parts of Brazil and India according to their actual latitudes.
