Magnus Maximus (re. 383~388), also known as Macsen Wledig in Welsh, was one of the many usurping emperors of the late Roman Empire. Before taking the throne, he was a distinguished general in Britannia. Although he is largely remembered as a usurper who was eventually executed, he left a huge footprint in British history and Welsh legend.

This drawing is largely based on statues of late Roman emperors wearing armor. He is wearing a gold diadem, and his cloak is secured by a crossbow-shaped brooch. His cuirass is made of bronze scales (lorica squamata), and old-fashioned pteruges fringes hang at shoulders and waist. Long-sleeved tunic and trousers are typical late Roman fashion.
