Alexander, or Alexandros (Άλέξανδρος) was a Byzantine and Eastern Roman emperor of the 10th century. His short reign was marked by attacks from the Abbasid Caliphate and Simeon I of Bulgaria. He allegedly died of excessive eating and drinking. Some even say he died from a particularly exhausting tennis game. It is a mystery to me how such an unremarkable, if not terrible, emperor can have such a unique and interesting mosaic.
