Calapoda, Giorgio Sideri (fl. 1537 - 1565)

Giorgio Sideri, also known as Calapoda (fl. 1537–1565) was a Cretan cartographer, though he lived and worked in Venice. His surviving navigational and hydrographical work is wholly manuscript, dating between 1537 to 1565; he authored no printed work. His manuscript of his home island provided the basis for virtually every map of Crete produced in the 17th and early 18th century. His most recently famous work was a 1541 manuscript copy of a fifteenth-century portolan chart by Fra Mauro, not known to have survived in any other form.
