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.
Scanian Law
Codex Runicus ("AM 28 8vo") is the most famous of several manuscripts from the 13th to 15th centuries containing handwritten copies of the Scanian Law. The second part of the Codex Runicus manuscript consists of two short historical texts: a fragment of a list of Danish kings and a chronicle beginning with the legendary Danish king Hadding's son Frode and ending with Eric VI of Denmark. Following the historical texts is a description of the oldest border between Denmark and Sweden and at the last leaf, the notes and words of the oldest preserved piece of music known in Denmark, a verse with accompanying musical notation on a four-line staff - the first musical notations written in Scandinavia.
