U+10141 "𐅁" Greek Acrophonic Attic One Half Unicode Character

U+10141 "𐅁" Greek Acrophonic Attic One Half is a numeral symbol from the ancient Greek acrophonic system of numeration, specifically used in Attica (the region around Athens) to represent the fraction one half. This character originates from a system where numbers were denoted by the first letter of their name in Greek; for example, the symbol for one half is derived from the initial letter of the word for "half," which is *ἡμίετον* (hēmíeton) or a similar term, and it was employed in inscriptions and financial records alongside other acrophonic numerals. It belongs to the Unicode block Ancient Greek Numbers and serves as a historical artifact of early accounting and mathematical notation, distinct from modern Arabic or Roman numerals. The character is encoded in the Supplementary Multilingual Plane and requires appropriate font support for proper display, offering a glimpse into the numerical practices of classical Athens.
