Fortune-telling, the forecasting of future events or the delineation of character by methods not ordinarily considered to have a rational basis. Evidence indicates that forms of fortune-telling were practiced in ancient China, Egypt, Chaldea, and Babylonia as long ago as 4000 BCE. Prophetic dreams and oracular utterances played an important part in ancient religion and medicine.
Predictive methods of fortune-telling include astrology (interpretation of the movements of heavenly bodies as influences on earthly events), numerology, and the utilization of objects such as playing cards, tea leaves, crystal balls, dice, fire, water, and scattered salt. Fortune-telling as a process of character analysis can take such forms as graphology (study of handwriting), physiognomy (study of facial characteristics), phrenology (study of contours on the skull), and palmistry (study of lines on the palm of the hand).
