Palmistry is one of the many arts that humans use to try and understand their past and present and foretell their future. It is such an ancient art that history doesn't record exactly when humankind first practiced it as a form of divination. In the oldest traditions, the art of reading the hand was called cheiromancy. The term "palmistry" came into popular use in the seventeenth centrury1.
History does record that palmistry, also known as hand reading, is found in Greek, Roman, Arabic, Indian, Chinese, and Japanese cultures. One legend tells that Aristotle (384-322 B.C.E.) presented a golden treatise on palmistry to Alexander the Great (356-323 B.C.E.) who used it to read the palms of his officers. Other historical figures that practiced palmistry are Napoleon Bonaparte, Hippocrates, Homer, and Galen2. Although modern science and skeptics doubt its validity, palmistry is still highly regarded and practiced in many Oriental cultures1.
Read horizontal lines from the thumb side across, vertical lines from the wrist up3.
Also called the "realistic" hand and usually the one you use for writing, the dominant hand is read first to identify the subject's past life and present condition4, 5. The other hand, the "receptive" hand, is read second to define the talents of the individual and divine the individual's future. Although some palmists read the whole hand, including the shape of the hand, wrist lines, fingers, and even finger nails3, the lines of the hand and the mounts are most often read.
The mounts of the hand are those fleshy parts directly below the fingers, the thumb, and the fleshy part of the hand below the little finger. The planetary names of the mounts remind us of palmistry's close association to another form of divination, astrology7.
Palmists believe that the lines of the hand are intricately linked to the flow of human consciousness. The major lines of the hand are the life line, head line, Girdle of Venus, sun line, mercury line, and fate line. Other lines (chains, crosses, breaks, and forks) along with unlined areas (islands) of the hand are read to show disruptions and changes in the subject's life.

The human hand is our link to the world outside our bodies. It touches, grasps, holds, and carries. It is little wonder that through the ages, people all over the world have sought to understand the its lines in the possibility that these hardworking extremities are additionally links to the inner mysteries of life.
