Palmistry is the practice of fortune-telling through the study of the palm. Also known as palm reading, chiromancy, chirology or cheirology, the practice is found all over the world, with numerous cultural variations. Those who practice palmistry are generally called palmists, hand readers, hand analysts, or chirologists.
There are many—and often conflicting—interpretations of various lines and palmar features across various teachings of palmistry. Palmistry is widely viewed as a pseudoscience due to various contradictions between different interpretations and the lack of evidence for palmistry's predictions.
Palmistry is a practice common to many different places on the Eurasian landmass; it has been practiced in the cultures of Sumeria, Babylonia, Arabia, Canaan, Persia, India, Nepal, Tibet and China.
The acupuncturist Yoshiaki Omura describes its roots in Hindu astrology (known in Sanskrit as jyotish), Chinese Yijing (I Ching), and Roma fortune tellers. Several thousand years ago, the Hindu sage Valmiki is thought to have written a book comprising 567 stanzas, the title of which translates in English as The Teachings of Valmiki Maharishi on Male Palmistry. From India, the art of palmistry spread to China, Tibet and to other countries in Europe.
Palmistry also progressed independently in Greece where Anaxagoras practiced it. Aristotle (384–322 B.C.E.) reportedly discovered a treatise on the subject of palmistry on an altar of Hermes, which he then presented to Alexander the Great (356–323 B.C.E.), who took great interest in examining the character of his officers by analyzing the lines on their hands. A chapter of a 17th-century sex manual, misattributed to Aristotle, is occasionally incorrectly cited as being the treatise in question. The text it is not contained in his canonical works.
In Renaissance magic, palmistry (known as "chiromancy") was classified as one of the seven "forbidden arts", along with necromancy, geomancy, aeromancy, pyromancy, hydromancy, and spatulamancy (scapulimancy).
