Palmistry or chiromancy (also spelled cheiromancy, Greek kheir hand ; manteia divination ), is the art of characterization and foretelling the future through the study of the palm, also known as palm reading, or chirology. The practice is found all over the world, with numerous cultural variations. Those who practice chiromancy are generally called palmists, palm readers, hand readers, hand analysts, or chirologists. The information outlined below is briefly representative of modern palmistry; there are many ? often conflicting ? interpretations of various lines and palmar features across various schools of palmistry. Hand shape:- Depending on the type of palmistry practiced, and the type of reading being performed, palmists may look at various qualities of the hand, including the shapes and lines of the palm and fingers; the color and texture of the skin and fingernails; the relative sizes of the palm and fingers; the prominence of the knuckles; and numerous other attributes of the hands. In most schools of palmistry, hand shapes are divided into four or 10 major types, sometimes corresponding to the Classical elements or temperaments. Hand shape is believed to indicate character traits corresponding to the type indicated (i.e., a "Fire hand" would exhibit high energy, creativity, short temper, ambition, etc. - all qualities believed to be related to the Classical element of Fire). Although variations abound, the most common classifications used by modern palmists:- Earth :- Hands are generally identified by broad, square palms and fingers, thick or coarse skin, and ruddy color. The length of the palm from wrist to the bottom of the fingers is usually equal to the length of the fingers. Air :- Hands exhibit square or rectangular palms with long fingers and sometimes protruding knuckles, low-set thumbs, and often dry skin. The length of the palm from wrist to the bottom of the fingers is usually equal to the length of the fingers. Water :- Hands are seeable by the short, sometimes oval-shaped palm, with long, flexible, conical fingers. The length of the palm from wrist to the bottom of the fingers is usually less than the width across the widest part of the palm, and usually equal to the length of the fingers. Fire :- Hands are characterized by a square or rectangular palm, flushed or pink skin, and shorter fingers. The length of the palm from wrist to the bottom of the fingers is usually greater than the length of the fingers.
