Nice old color example of Mortier's maps showing the Red Sea and the Island and Fortifications of Mombasa in Kenya.
The map is oriented to the west and provides remarkable detail for the region.
Pierre, or Pieter, Mortier (1661-1711) was a Dutch engraver, son of a French refugee. He was born in Leiden. In 1690 he was granted a privilege to publish French maps in Dutch lands. In 1693 he released the first and accompanying volume of the Neptune Francois. The third followed in 1700. His son, Cornelis (1699-1783), would partner with Johannes Covens I, creating one of the most important map publishing companies of the eighteenth century.
