Map of the world by Henricus Martellus Germanus

Henricus Martellus Germanus is the latinized name of Heinrich Hammer, a German geographer and cartographer who lived and worked in Florence from 1480 to 1496.

Around 1489 or 1490, he produced a world map which was remarkably similar to the terrestrial globe later produced by Martin Behaim in 1492, the Erdapfel. Both show novel adaptions of the existing Ptolemaic model, opening a passage south of Africa and creating an enormous new peninsula east of the Golden Chersonese (Malaysia). Both possibly derive from maps created around 1485 in Lisbon by Bartolomeo Columbus.

One of his two manuscript world maps, 201 cm x 122 cm in size, rediscovered in 1960, was donated to Yale's Beinecke Rare Book and Manuscript Library.[1]

The other similar manuscript world map is in the British Library.[2]

Martellus also in 1484 produced an Insularium Illustratum ("Illustrated Book of Islands"), containing maps.[3]
