an amazing stone that appears to be the casualty list from the battle of Marathon. The inscription is written
in boustrephon and diagonally(see comments for update), and was acquired by Herodes Atticus when he honored his home town of Marathon by constructing a great tumulus over the burial site of the Athenian dead.
This is to make a point. Herodes Atticus, who had more money than God, did a great deal of building across Greece which allowed him innumerable sources of art for the swollen collections at his various villas, including those at Marathon and Kefissia.
