Ägypten Ortelius, Abraham, ab 570, 22,9 x 31,8 cm This is a double map of both The Nile delta region and the city of Tunis and surrounding area. The top map contains colored political boundaries and a grid reference system typical of Orelius’s maps. The many settlements along the Nile are clearly named. The bottom map is more of an artistic representation. No grid or rhumb lines are present for navigation. The sea is filled with classical vessels. In 1596 the renowned cartographer Abraham Ortelius produced his new revised edition of Claudius Ptolemy's "Geographia". In 1597 followed the Cologne edition of this work. Ptolemy (90-168 AD), was a Greek mathematician, geographer, astronomer, astrologer and philosopher, and probably worked in Alexandria. His most important work "Geography Outline", was better known as "Geographia". This is the principle classical period, atlas style publication of the ancient world. Ptolemy's work was based on parts of older sources."Geographia" contained 27 "Maps" (1x world, 10x Europe, 4x Africa and 12x Asia) and descriptions of about 8,000 places. It used an innovative system of coordinates and was one of the first attempts to present the earth as round. Like many ancient works, original copies of this atlas were lost and then rediscovered by the Western world in the 14th Century during the early Renaissance period. Representations of Ptolemys work were was used as the basis for many maps that were printed in numerous editions throughout Europe. It was not until the 16th Century that cartographers broke away from a geocentric "Ptolemaic world view" and started to draw on new found discoveries and methods to represent the world.
