U+10170 "𐅰" Greek Acrophonic Naxian Five Hundred Unicode Character

U+10170 “𐅰” Greek Acrophonic Naxian Five Hundred is a historical numeral symbol from ancient Greece, specifically used in the acrophonic or “Herodianic” numeral system of Naxos, where it represented the value 500. This system derived its symbols from the first letters of the words for numbers, and in this case, the glyph resembles an archaic form of the letter pi, likely standing for the Greek word “πεντακόσιοι” (pentakósioi), meaning five hundred. The character is part of the Ancient Greek Numbers block in Unicode, preserving a glimpse into the diverse local numeral traditions of classical antiquity before the adoption of the more widespread alphabetic numerals.
