Lamellar and cataphract armour

[Theodosius the Great]

And I've found that six of them may depict emperors wearing lamellar armor. Some of them may be fancy robes studded with jewels but others seem to show a plated cuirass. The earliest one I've seen dates to the early 4th century.

You can view all six of them :
