Severus Alexander, also known as Alexianus, the son of Julia Mamaea and grandson of Julia Maesa, was adopted and made Caesar in AD 221. He then assumed the name Marcus Aurelius Alexander, was proclaimed Augustus the following year and added the name Severus. Under his relatively calm reign various public construction in Rome took place, ie. the rebuilding of the Colosseum and the construction of the Nymphaeum. When a new wave of Persian expansion threatened the empire in AD 235, both Severus Alexander and his mother were murdered by discontented troops on the German frontier.

On his early coinage a beardless Severus Alexander is depicted with long oval features, a pointed chin, long arched brows, full lips and a nose with a bump at the bridge.
