Definition: The word "antheximeter" is a Greek term referring to a measurement unit used for measuring human height in ancient Greece, primarily by military men during battles. It was established with a system that divided people into three categories: the demi-god (2.46 meters tall), the demi-goddess (3.10 meters tall), and the demi-kratos (5.78 meters tall). This unit was also used for determining the length of one's legs in ancient Roman times, where it measured from the knee to the ankle at a height of 2.46 meters.
