Sylvanus' map of the northern parts of Europe, from the Rhine in the west, the Danube in the south and the Vistula in the east, is one of the earliest obtainable maps of the region and the first printed in two colors.
The map is also one of the earliest maps to show any part of Scandinavia and an important early map for its treatment of the Baltic Sea and the western part of Poland. The Sylvanus edition of Ptolemy is one of the earliest to include maps with modern geographical updates.
The map appeared in Sylvanus' Claudii Ptholemaei Alexandrini liber Geographicae . . . published in Venice in 1511. A nice example of a map which very rarely appears on the market.
