Multiocular O (ꙮ) is a unique kind of cyrillic O. It is like Monocular O multiplied ten times. This type of O is only found in one book from the 15th century, in the Old Church Slavonic phrase серафими многоꙮчитїи (abbreviated мн̑оꙮ҆читїи̑; meaning many-eyed “Seraphim”. The phrase is in a copy of the Book of Psalms from around 1429, now found in the collection of the Trinity Lavra of St. Sergius.
It was suggested to be added to Unicode in 2007. Unicode added it as character U+A66E in Unicode version 5.1 (2008). The original version added only had seven eyes and sat on the baseline. However, in 2021, someone tweeted that the version added was wrong, which led the linguist Michael Everson to say that the character in the original 1429 manuscript was actually made up of ten eyes, instead of 7. In 2022, it was suggested to change it, and it was updated in Unicode 15.0, to have ten eyes and to extend the character below the baseline. However, not all fonts have updated to support the new ten-eyed version, as of August 2025[update].
The character was written wrongly into Unicode and most fonts have not updated to show the correct number of circles.
