Saint Demetrius or Saint George, Byzantine Steatite Icon, 11th or 12th Century
An 11th century carved ikon of St George, in scale armour, with arm and body protection made of what appears to be a form of lamellar,
and closely resembles that seen on the St George ikon from Vatopedi monastery.

A 12th century depiction of a military saint.
Manuscripts and murals depict Byzantine soldiers in apparently dated equipment throughout this period, so are not generally considered accurate.
The consensus appears to be that though their portrayal of helmets, swords and shields is reliable, the armour is deliberately archaic.
Such selective traditionalism, however, is improbable, and what seems more likely is that - barring exceptions obvious to even an untrained eye -
many contemporary pictures are more accurate than is often supposed.
