Oxyrhynchus hymn

The Oxyrhynchus hymn is a Christian Greek religious song with lyrics and musical notation from the 3rd century AD. The hymn was written on a manuscript that was discovered in 1918 in modern Egypt, published in 1922, and now preserved in Oxford University.
Description.
The lyrics of the Oxyrhynchus hymn were written in the Greek language. They use poetry to summon silence in praise of the Holy Trinity, a motif of ancient Greek hymns called "cosmic stillness". The music of the Oxychynchus hymn is composed in Greek vocal notation. Overall, the Oxyrhynchus hymn illustrates the historical continuity of Greek culture where educated Christian Greeks accepted and used the musical notation of their ancient Greek ancestors. Also, it is the only surviving piece of Christian Greek music from the first 400 years of Christianity.
