Sylvanus' map of region west of the Black Sea, north of the Aegean Sea and east of the Adriatic is one of the earliest obtainable maps of the region and the earliest printed in two colors.
The map includes the regions which includes parts of Turkey, Greece, Bulgaria, Romania, Serbia, Kosovo, Macedonia, Albania, Montenegro and Croatia.
The map appeared in Bernardus Sylvanus's Claudii Ptholemaei Alexandrini liber Geographicae . . ., published by Jacobus Pentius de Leucho in Venice in 1511. Sylvanus recognized that the geography shown in prior works was out-dated, attempted to update the maps by inserting more modern information, often from contemporary manuscript sources, which he super-imposed over the Ptolemaic material, creating an unusual effect. An innovative feature is that the maps, which are printed from woodblocks, are printed in two colours, red and black, with the principal names in red. In addition to the Ptolemaic set, Sylvanus also included a modern map of the World, on a cordiform, or heart-shaped projection. Visible along the western border are eastern South America, Cuba and Hispaniola, and the tip of Labrador or Newfoundland.
The net result of Sylvanus' innovations is one of the earliest variations for the presentation of topographical details on a printed map.
