This is one of three inscriptions/plaques that were found in the synagogue at Andriace. It measures 2.9 x 1.4 ft. (87 x 44 cm.). Note in the main panel the seven branch candelabrum (menorah) that is standing upon a tripod (two legs are visible)—these are typical symbols of Judaism during this period (compare the capital found at Capernaum in Israel). On the right is a shofar (ram's horn) and to the left an etrog and a lulav (symbols associated with the feast of Succoth [tabernacles]) are visible. The excavators believe they have discovered a mate to this (with a completion of this inscription, but only partially preserved in its upper portion; see Çevik et al. below).
Also, to the left of the inscription a smaller menorah, shofar, and lulav are visible (click here for details).
The excavator believes that the synagogue was located in the upper floor of this building and that the inscriptions/plaques fell from that floor to where they were found (commentary/data from the museum in Antalya).
A report on the excavations and inscriptions at Andriace can be found in Nevzat Çevik, Özgü Çomezoglu, Hüseyin Sami Öztürk, and Inci Türkoglu, "A Unique Discovery in Lycia: The Ancient Synagogue at Andriake, Port of Myra." Adalya XIII (2010), 335–66.
