Oxyrhynchus hymn
The Oxyrhynchus hymn (or P. Oxy. XV 1786) is the earliest known manuscript of a Christian Greek hymn to contain both lyrics and musical notation. The papyrus on which the hymn was written dates from around the end of the 3rd century AD. It is on Papyrus 1786 of the Oxyrhynchus papyri, originally kept at the Papyrology Rooms of the Sackler Library, Oxford, which was renamed the Bodleian Art, Archaeology and Ancient World Library in 2022. The manuscript was discovered in 1918 in Oxyrhynchus, Egypt, and later published in 1922.
