Seikilos epitaph
The Seikilos epitaph is the oldest surviving complete musical composition, including musical notation, from anywhere in the world. The epitaph has been variously dated, but seems to be either from the 1st or the 2nd century AD. The song, the melody of which is recorded, alongside its lyrics, in the ancient Greek musical notation, was found engraved on a tombstone (a stele) from the Hellenistic town Tralles near present-day Aydın, Turkey, not far from Ephesus. It is a Hellenistic Ionic song in either the Phrygian octave species or Iastian tonos. While older music with notation exists (for example the Hurrian songs), all of it is in fragments; the Seikilos epitaph is unique in that it is a complete, though short, composition.
Cædmon
Cædmon's only known surviving work is "Cædmon's Hymn", the nine-line alliterative vernacular praise poem in honour of God which he supposedly learned to sing in his initial dream. The poem is one of the earliest attested examples of Old English and is, with the runic Ruthwell Cross and Franks Casket inscriptions, one of three candidates for the earliest attested example of Old English poetry. It is also one of the earliest recorded examples of sustained poetry in a Germanic language. In 1898, Cædmon's Cross was erected in his honour in the graveyard of St Mary's Church in Whitby.
