The following excerpt comes from a description of the kingdom of Ghana, written by an 11th-century Arab from Spain, Al-Bakri:

In the king's town, and not far from his court of justice, is a mosque where the Muslims who arrive at his court pray. Around the king's town are domed buildings and groves and thickets where the sorcerers of these people, men in charge of the religious cult, live. In them too are their idols and the tombs of their kings.
