Divination by walking in a circle until dizziness caused a person to fall and this was interpreted in various ways.

Originally, it was performed by people who moved around a circle marked with letters or symbols, until they became dizzy and stumbled, thus spelling out words or enabling a diviner to interpret the symbols. Some authorities say that it was from this concept that came the wild, whirling dances by fanatics who uttered prophecies after collapsing in a state of complete exhaustion.
