palm
Quick Summary
The ancient Egyptians used a measurement system that included the "palm." This unit of length was based on the breadth of a hand, including the thumb. A royal cubit, a standard linear measurement in ancient Egypt, was equivalent to 28 digits, with four digits making up one palm. The palm was also used in other ancient cultures, including the Hebrews, Greeks, and Romans. The Romans used the word "palmarius" to describe something extraordinary, inspired by the palm leaf given to victors in sports competitions, and this word is related to the palm of the hand.123
