About this source

What it is

This mosaic, made around 547, decorates the Basilica of San Vitale in Ravenna. It shows a haloed figure identified as Emperor Justinian I, dressed in purple and gold, surrounded by clergy, court officials and soldiers.

Made from small coloured glass and stone tiles called tesserae, the portrait was created by Byzantine craftsmen while Justinian still ruled the empire.

Why it matters

The mosaic is one of the few surviving lifetime images of Justinian and shows exactly how he wanted to be seen: as a ruler who united imperial and religious authority. Its placement in a church in Italy, far from Constantinople, also reflects his ambition to reassert control over the western Mediterranean.

Look closer

  • Why might Justinian want to be shown surrounded by soldiers and bishops together?
  • What does the halo suggest about how he wanted to be seen?
  • Who do you think this image was made for, and what message was it meant to send?
