U+037B "ͻ" Greek Small Reversed Lunate Sigma Symbol is a typographic variant of the Greek letter sigma, specifically representing an archaic or alternative form used in early Greek epigraphy and manuscripts. Unlike the standard lowercase sigma, which typically has a rounded shape, this reversed lunate sigma resembles a rotated version of the lunar or crescent-shaped sigma, often employed as a numeral symbol in ancient contexts. In Unicode, it belongs to the Greek and Coptic block and is classified as a lowercase letter, though its use in modern typography is primarily scholarly or historical rather than for contemporary Greek writing.
