The Bitola Triodion is a Middle Bulgarian Glagolitic manuscript that contains a triodion from the late 12th century.
In 1898, the manuscript was brought to the in Bitola from a nearby village, along with other Slavic and Greek manuscripts.[1] Historian Yordan Ivanov found it in Bitola in 1907. It is now kept in the library of the Bulgarian Academy of Sciences in Sofia.[2]
The triodion contains 101 leaves of parchment, each sized to 27.5 x 19.5 cm. According to Ivanov, it was written in the village of by Georgi Gramatik.[3] Along with usual service prayers, it contains a hymographic cycle of Konstantin of Preslav. It is written in Cyrillic with traces of Glagolitic, which is considered to be a characteristic feature of manuscripts from the Bulgarian region.
Some scholars assume that it is a direct copy of an older, Glagolitic book.[4] The document contains musical notation, and a frequent use of the self-theta (Θ), which is written in black and red ink. The sign is placed above individual words to inform singers of musical ornamentation.[5]
