Multiocular O (ꙮ) is an exotic glyph variant of the Cyrillic letter O. This glyph variant can be found in certain manuscripts in the Old Church Slavonic phrase "серафими многоꙮчитїи" (serafimi mnogoočitii, "many-eyed seraphim"). It was documented by Yefim Karsky from a copy of Psalms from around 1429, now found in the collection of the Trinity Lavra of St. Sergius. It was proposed for inclusion into Unicode in 2007 and incorporated as character U+A66E in Unicode version 5.1 (2008).
