Hadrian's portraits

Hadrian's portraiture shows him as the first Roman emperor with a beard. Most emperors after him followed his lead. 10 different portrait types are known of Hadrian. A juvenile type with curly hair, broad side burns and a light moustache (but a free chin) was shown on coins later in his life on rare aurei, but likely reflects an early portrait before he became emperor. His first portrait type as Caesar and Augustus used on coins in Mid 117AD shows again broad sideburns merging into a strong moustache and still a free chin. The beard thus resembles beard styles popular in the 19th century like emperor Franz Josef of Austria.

This is then followed by portraits showing Hadrian with a short, well groomed full beard until his death. Of note his portraits do not age during his reign. See other portrait images of Hadrian in this article for examples of the later Hadrian portraits.
