the really important artifact(s) from the synagogue at dura europos is(are)
Dura-Europos synagogue The Dura-Europos synagogue (or "Dura Europas", "Dura Europos" etc.) is an ancient synagogue uncovered at Dura-Europos, Syria, in 1932. The last phase of construction was dated by an Aramaic inscription to 244 CE, making it one of the oldest synagogues in the world. It is unique among the many ancient synagogues that have emerged from archaeological digs as the structure was preserved virtually intact, and it had extensive figurative wall-paintings, which came as a considerable surprise to scholars. These paintings are now displayed in the National Museum of Damascus.
