Sylvanus' map of Persia, is one of the earliest obtainable maps of the region and the first printed in two colors.
The Sylvanus edition of Ptolemy is one of the earliest to include maps with modern geographical updates. The map has been printed on two leaves, which have here been rejoined and backed with Japan paper on the verso, and trimmed into the right margin, with minor loss of text. In all, this remains a good example of a map which very rarely appears on the market. The map appeared in Sylvanus' Claudii Ptholemaei Alexandrini liber Geographicae . . ., publish in Venice in 1511.
