Multiocular O (ꙮ) is a rare Cyrillic glyph found in a single 15th-century manuscript, in the Old Church Slavonic phrase серафими многоꙮчитїи (abbreviated мн̑оꙮ҆читїи̑; serafimi mnogoočitii, “many-eyed seraphim”). It was documented in 1928 by Yefim Karsky in a Psalter dated to around 1429, now preserved at the Trinity Lavra of St. Sergius.
The many-eyed letter in the original manuscript
The character was encoded as U+A66E in Unicode 5.1 (2008). The original Unicode reference glyph showed seven circles, but the historical manuscript contains ten. In 2022, the Unicode chart was corrected to reflect the ten-circle design, though some fonts may still display the earlier version.
