Palmistry, also known as chiromancy (from the Greek: χείρ, kheír ["hand"] + -μαντεία, manteia ["divination, soothsaying"]) or chirology (-λογία, -logia, "study of"), is the art and study of palm reading, the analysis of the lines of the palm of a subject's hand to determine their character or predict their future. It has been practiced across cultures since antiquity throughout Europe, Africa, and Asia.
