This fine engraved map of Wales by Pieter van den Keere was first issued in the Latin edition of Jodocus Hondius’ edition of Gerard Mercator’s ‘Atlas Sive Cosmographiae’ issued in 1607 as an additional plate. This example is from the sixth volume of the ‘Atlas Novus’ issued c.1662, a relatively rare issue. This represents the plates third state in which the map is heavily revised. The title is now moved to the upper right, the stippled sea is erased and a new compass rose in positioned in the Irish Sea. The outline of the map is derived from Humphrey Lloyd’s as published by Abraham Ortelius, the first modern map of Wales. Degrees of longitude and latitude remain in the borders.
