This map was created by German cartographer August Heinrich Petermann in 1860, including for the first time the information gathered by Theodor von Heuglin on his journey along the Egyptian coast of the Red Sea in 1857.

It is clear that Petermann had a great deal of information about the western coast of the Red Sea, given the high level of detail of this coast compared to the eastern coast. In the upper left map, the author shows the countries that occupied this territory at that time, with Egypt and its dependencies shown in orange and the Ottoman Empire and its dependencies in yellow.

The map also includes details of ten of the most important locations in the Red Sea at that time, according to the information available to the author. These places include Suakin (Sudan), Massawa (Eritrea), Adulis (Eritrea), the island of Perim (Yemen), Quseir al-Qadim / Mios Hormos (Egypt) and Mocha (Yemen).
