Quarta Affrice tabula. Claudius Ptolemy; Nicolaus Germanus. Ulm: 1486
Northern and Central Africa and the Mediterranean Sea are shown, as well as the Nile River, the Red Sea, and the Arabian Peninsula in a trapezoidal projection. Southern Africa is labeled “Terra Incognita” at the bottom. This map is one of several based on Ptolemy's Geographike (ca. 120–150 AD), printed in Vicenza, Bologna, Florence, Rome and Ulm between 1475 and 1486. These Ptolemaic maps appeared after the fall of Constantinople to the Ottoman Turks in 1453.
