Greek ring of Thrace

In my previous post I mentioned the discovery of various archaeological finds in Bulgaria this past weekend. The ring itself has a clear inscription in Greek. It may have been used as an official stamp, since, from what I can read, the letters are depicted in reverse. The inscription reads: ΤΗΡΗΤΟΣ ΣΗΥΣΑ (Τηρητος Σηυσα).
