Gerardus Mercator, 1619

Mercator is the most famous of the early cartographers, largely on account of "Mercator’s projection", which provided a way of showing the globe in two-dimensional form (at the expense of exaggerating the size of the polar regions, while reducing that of the tropical ones). Much of his map of Ethiopia is evidently taken from Ortelius, though it shows that Ethiopia had by this time lost its access to the Red Sea.
