These wooden panels are the finest and most complete examples to survive from the Early Byzantine period, having been preserved in the dry sands of Egypt. The panels, made for a cupboard or cabinet (or possibly used as window shutters), each have richly carved medallions of interlacing bands set with rosettes or eagles. A very similar pair of wooden doors is in Athens, Benaki Museum, inv. 9083.
