Palmistry consists of the practice of evaluating a person's character or future life by "reading" the palm of that person's hand. Various "lines" ("heart line", "life line", etc.) and "mounts" (or bumps) purportedly suggest interpretations by their relative sizes, qualities, and intersections. In some traditions, readers also examine characteristics of the fingers, fingernails, fingerprints, and palmar skin patterns (dermatoglyphics), skin texture and color, shape of the palm, and flexibility of the hand.
A reader usually begins by reading the person's dominant hand (the hand he or she writes with or uses the most, which is sometimes considered to represent the conscious mind, whereas the other hand is subconscious). In some traditions of palmistry, the other hand is believed to carry hereditary or family traits, or, depending on the palmist's cosmological beliefs, to convey information about past-life or karmic conditions.
The basic framework for "classical" palmistry (the most widely taught and practiced tradition) is rooted in Greek mythology. Each area of the palm and fingers is related to a god or goddess, and the features of that area indicate the nature of the corresponding aspect of the subject. For example, the ring finger is associated with the Greek god Apollo; characteristics of the ring finger are tied to the subject's dealings with art, music, aesthetics, fame, wealth, and harmony.
