Superb early map covering Down and Antrim Counties in Northern Ireland. This was one of five Irish maps Gerard Mercator designed for the second part of his Atlas. It is beautifully engraved with a moiré pattern in the sea, strong topographical features in the interior, and ornamented with a title cartouche incorporating the distance scale. French text on verso.
