From seven eyes to ten: the strange evolution of the Cyrillic Multiocular O
In short: Medieval scribes occasionally embellished the Cyrillic letter O with elaborate, symbolic flourishes. While most variants served simple orthographic roles, one unique character—the Multiocular O—was designed to represent the many-eyed seraphim. Recently, digital standards were updated to correct a long-standing error regarding the exact number of eyes it contains.
The Cyrillic alphabet contains several rare glyph variants of the letter O, many of which appeared in early manuscripts to denote specific meanings or positions. The Monocular O, for instance, featured a dot inside and was used in words like the root for 'eye,' while the Binocular and Double Monocular O variants were employed in dual or plural forms. These characters were formally incorporated into Unicode in 2008, following a 2007 proposal.
The most striking of these is the Multiocular O, a hapax legomenon found in a single 15th-century manuscript known as the Buslaev Psalter. Originally documented by Yefim Karsky in 1928, the manuscript was once thought to date to 1429, though modern estimates place it between c. 1487 and c. 1490. The character was intended to illustrate the 'many-eyed seraphim' in the phrase 'serafimi mnogoočitii.' For years, the Unicode representation featured seven eyes, but a 2021 social media post prompted linguist Michael Everson to re-examine the original text. He discovered the character actually contained ten eyes, leading to a 2022 update in Unicode 15.0 to accurately reflect the original design.
Other variants served more functional roles. The Broad On, or 'Round Omega,' acts as a positional variant in Church Slavonic, often appearing at the start of words or roots. Unlike the exotic multi-eyed variants, the Broad On has been used consistently since the mid-17th century, sometimes functioning as a numerical sign for 70. Meanwhile, the Crossed O was specifically used in the word for 'around,' referencing the word for 'cross' contained within it. These characters demonstrate how medieval scribes used graphic design to imbue text with layers of visual meaning, transforming a simple vowel into a tool for theological or structural emphasis.
