Have a look here. http://en.wikipedia....eikilos_epitaph The Seikilos epitaph is the oldest surviving example of a complete musical composition, including musical notation, from anywhere in the world. It was written by Seikilos around 200 BC and 100 AC. So, I think you can use it freely. You also have the notes. Of course you can't use the video I posted on youtube. These are the lyrics, first in ancient greek, then a transliteration and english translation, which somehow I found interesting for a strategy game... Ὅσον ζῇς, φαίνου, Hoson zês, phainou, While you live, shine, μηδὲν ὅλως σὺ λυποῦ· mêden holôs su lupou; have no grief at all; πρὸς ὀλίγον ἐστὶ τὸ ζῆν, pros oligon esti to zên, life exists only for a short while, τὸ τέλος ὁ xρόνος ἀπαιτεῖ. to telos ho chronos apaitei. and time demands its toll. Here is another version, with correct greek accent (listen up to 1:00)
P.S. 1) Well, it is also included in civilization V, as I just found without lyrics:(
2) Since I am greek, I could probably also help with some greek voices, for which I find the accent a bit weird...!
