This illustrated reference surveys more than one hundred traditions that people have used to seek knowledge of the future, interpret character or find meaning in signs. It introduces familiar practices such as astrology, palmistry, tarot, numerology, dream interpretation and reading playing cards, while also describing less widely known forms of divination. Diagrams and examples explain the symbols, systems and basic procedures associated with each method, placing many of them in their historical and cultural setting. The book is intended as an accessible overview rather than proof that predictions are scientifically reliable.
