Al Bakri's Description of Ghana
The king's residence comprises a palace and conical huts, the whole surrounded by a fence like a wall. Around the royal town are huts and groves of thorn trees where live the magicians who control their religious rites. These groves, where they keep their idols and bury their kings, are protected by guards who permit no one to enter or find out what goes on in them.
None of those who belong to the imperial religion may wear tailored garments except the king himself and the heir-presumptive, his sister's son. The rest of the people wear wrappers of cotton, silk or brocade according to their means. Most of the men shave their beards and the women their heads. The king adorns himself with female ornaments around the neck and arms. On his head he wears gold-embroidered caps covered with turbans of finest cotton. He gives audience to the people for the redressing of grievances in a hut around which are placed 10 horses covered in golden cloth. Behind him stand 10 slaves carrying shields and swords mounted with gold. On his right are the sons of vassal kings, their heads plaited with gold and wearing costly garments. On the ground around him are seated his ministers, whilst the governor of the city sits before him. On guard at the door are dogs of fine pedigree, wearing collars adorned with gold and silver. The royal audience is announced by the beating of a drum, called daba, made out of a long piece of hollowed-out wood. When the people have gathered, his co-religionists draw near upon their knees sprinkling dust upon their heads as a sign of respect, whilst the Muslims clap hands as their form of greeting.
