Marcus Jordanus
Danish cartographer and mathematician
Marcus Jordanus (* ca. 1531 in Krempe; † 1595 in Krempe) was a Danish cartographer and mathematician.
Jordanus studied at the University of Copenhagen, where in 1550 he was appointed Professor of Mathematics. Among other things, he gave lectures on geodesy and dealt with the geography of Ptolemy. In 1552, he published a map with the printer Hans Vingaard in Copenhagen. This was one of the first printed maps of the Duchies of Schleswig and Holstein, and Abraham Ortelius referred to it in his Catalogus Cartographorum. The map is now lost, and no copies survive.
