People don't believe me when I say my mom's a palm reader in New Orleans. It's also called Chiromancy.
oh i didn't know that, i have always wanted to get my palm read
people who do it are called either pamists, palm readers, hand readers or even hand analysts but I like chirologist term a lot.
i have never heard that term. apparently its very old.  It is said to have been practiced in very early times by the Brahmins of India and to have been known to Aristotle, 
That's right, it actually comes from the term "kheir" in Greek meaning hand and "manteia" meaning divination. You can foretell someone's future this way.
So cheirognomy, the art of recognizing the type of intelligence from the form of the hands; cheirosophy, the study of the comparative value of manual formations; and cheiromancy, the art of divination from the form of the hand and fingers, and the lines and markings thereon.
It amazes me how many ancient studies and practices there are. Let's take Arithmacy, it's something used till this day, what would we do without numbers. apparently this term also comes from Greece.
wow the greeks had a lot of influence! Apparently The principal lines are those that separate the hand from the forearm at the wrist, which are known as the rascettes, or the lines of health, wealth, and happiness.
That's right, the practice itself  is found all over the world depending on the culture.
The popularity of palmistry was raised to a new height, especially in the English-speaking world, by "Cheiro," the public name of Count Louis Hamon (1866-1936), who was patronized by royalty and distinguished individuals of his time.
