Bianco world map
From Wikipedia, the free encyclopedia
Andrea Bianco was an Italian sailor and cartographer of the 15th century.
Andrea Bianco's atlas of 1436 comprises ten leaves of vellum, measuring 29 X 38 cm., in an 18th century binding. The first leaf contains a description of the Rule of Marteloio for resolving the course, with the "circle and square", two tables and two other diagrams. The next eight leaves contain various navigation charts. The ninth leaf contains a circular world map measuring 25 cm in circumference.
And the final leaf contains the Ptolemaic world map on Ptolemy's first projection, with graduation. Some believe Bianco's maps were the first to correctly portray the coast of Florida, as a macro-peninsula is attached to a large island labeled Antillia. Bianco also collaborated with Fra Mauro on the Fra Mauro world map of 1459.
