CIMRM 78-79 - Lion-headed statuette. Sidon. In the Louvre.
I.e. I, Flavius Gerontius, pater nomimos, set this up in the 500th year.
The "year 500" is uncertain. If it is the 500th year of the Seleucid Era (AS), then 500 AS = 188 A.D. If it is following a local Sidon year-table, it is 398 A.D.1
Another monument from the Sidon Mithraeum also has a similar dated inscription, CIMRM 76.
