Argyrus (or Argyros; c. 1000–1068) was a Lombard nobleman and Byzantine general. A son of the Lombard hero Melus, he was born at Bari around 1000. Upon the defeat of Melus, who had rebelled against the Byzantines, at the battle of Cannae in 1018, Argyrus and his mother were captured and taken to Constantinople as prisoners. He was out of confinement by 1038, when he returned to Apulia, then in an uproar over being pressed into service during the Byzantine invasion of Sicily. The Lombard troops returned with their Norman and Varangian comrades in 1039, alienated by General George Maniaches.
