There are about 35 African place names. The knowledge of the contour of Africa predates the European explorations of Vasco da Gama. In particular, the southern tip of Africa is quite clearly depicted, as well as a river which may correspond to the Orange River in Southern Africa. To the north of the African continent, beyond the unexplored "black" central mass, a pagoda is represented for the lighthouse of Alexandria, and the Arab word "Misr" for Cairo (al-Qāhira) and Mogadishu (Maqdashaw) are shown among others. The Mediterranean forms a clear shape but is not blackened unlike other sea areas. The Maghreb and the Iberian peninsula are depicted in detail while Genoa and Venice are omitted. There are over 100 names for the European countries alone, including "Alumangia" for the Latin word "Alemania" (Germany).
