Haruo - I shall look for the book in which I found the transcription of this skolion into modern notation. It was a school book, and if I remember correctly the musical signs were not dots on lines, but figures giving the heights of the tones. I think a picture of the old tombstone was attached. I only copied the melody in modern notation some 40 years ago for my collection.
I hope to find it in the library of my old school; fortunately the librarian is a neighbour of mine.
More when I have found it.
