A Byzantine palace, dating from the fifth to sixth centuries, has been excavated at Edessa in Turkey. What makes this palace particularly interesting is its quite fine mosaics, and for its "wall pictures depicting the Amazonian queens Hippolyte, Antiope, Melanippe and Penthesileia hunting in the forest." The caption to this photo of a mosaic suggests that it too depicted an Amazon, wearing royal purple, though I can't see the name as it's too small. The text says that the mosaic of Penthesilea has her riding a horse, which suggests a different panel. Also of interest is that the technique suggests links to Constantinople and the Imperial Court, the iconography suggests links to the Holy Land.
