Witch smellers, almost always women, were important and powerful people amongst the Zulu and other Bantu-speaking peoples of Southern Africa, responsible for rooting out evil witches in the area, and sometimes responsible for considerable bloodshed themselves. In present day South Africa their role has waned and their activities are illegal according to the Witchcraft Suppression Act, 1957.
If it was determined that some misfortune which had befallen the area had been caused by a witch, the chief summoned his people to a great meeting, in which they all sat in a circle, sometimes for four or five days. The witch smellers then took their places in the center.
The witch smellers wore extravagant costumes, usually including animal skins and feathered headdresses, and face paint. Their hair was heavily greased, twisted in complicated designs, and frequently dyed bright red. They often carried assegais and shields, and also a quagga-tail switch, the symbol of their profession.
Surrounded by a circle of women and girls who clapped their hands and droned a low, monotonous chant, the rhythm of which changed occasionally with the stamping of feet, the witch smellers proceeded to work themselves up into a frenzy. In this state, they spun, stalked and leapt, eventually touching one or more of the people with their switches, upon which the person was immediately dragged away and killed. All the living things in the accused witch's hut, human and animal, were also killed. Sometimes an entire kraal was exterminated in this way.
