Very lovely, decorative map of northern Ireland. This map was among five Irish maps Mercator designed for the second part of his Atlas. It is richly engraved with a moiré pattern in the seas and strong topographical features in the interior. The map is decorated with sailing ships and a sea monster and there is no title cartouche - only Mercator's imprint. Latin text on verso.
