Al-Idrisi was a noteworthy and original geographer. He used in a creative way the system of cylindrical projection of the Earth's surface, which was to be claimed some centuries later, in 1569, by the Flemish Gerard Mercator. Al-Idrisi's other merit, according to Udovitch is the extensive information he provides about contemporary Western Europe. Hitti also notes that Al-Idrisi's map places the sources of the Nile-supposedly discovered in the latter part of the 19th century in the equatorial highlands of Africa.
