Hi, Mahmud. I love finding parts of inscriptions, but they are frustratingly difficult to read and date. The lunate sigma and epsilon are a clue, suggesting to me
Roman Imperial (in the Greek speaking provinces), or early
Byzantine date, but I have not studied this subject so I really don't know much. A specialist in Greek
epigraphy might be able to
help. Searching on
Google for "
Roman Greek Marble
Inscription" brings up a lot of nice photos but might drive one crazy! In Translate.Google.com "ΓΟΝΟΣ"
comes up as "child" or "offspring", but I don't know how accurate that is for ancient Greek. Another
Forum member may be of more
help with this.
Good luck, and nice find.
