Byzantine Weapons and Warfare

[Laran]

Could the paintings of Piero della Francesca shed some light on the mystery of late Byzantine arms and armor? Those paintings were made in 1450 - 1460s. Some characters in them wear certain elements associated with the late Byzantine costume. So, if we discard some western items ( like Milanese suits of armor) and those which are artist's fantasy,could it be that he depicted some authentic items of Byzantine armor? Of course it's difficult to tell with certainty which items are fantasy and which are real. The issue is complicated by the fact that late Byzantines made use of western or western-influenced armor.
