Unicode Version 17.0

𐅘

U+10158 "𐅘" Greek Acrophonic Heraeum One Plethron is a numerical symbol from the ancient Greek acrophonic numeral system, specifically used to represent a measure of land area known as a plethron, which was derived from the temple of Hera at the Heraeum sanctuary. This character forms part of the ancient Greek numbers block in Unicode and is distinguished by its origin in the Heraeum inscription system, where it denoted a single plethron unit, roughly equivalent to about 100 feet in length or 10,000 square feet in area, depending on the local standard. Its inclusion in Unicode preserves a rare and historically significant notation used in classical Greek accounting and land surveying, offering a direct link to the administrative practices of ancient city-states.
