Emperor  

Elagabalus was a Roman emperor known for perverse and decadent behavior. Due to these associations with Roman decadence, Elagabalus became something of a hero to the Decadent movement in the late 19th century. Characterizing him and other historical persons in antiquity as "psychopaths" — for example, the five "mad emperors" of ancient Rome: Caligula, Nero, Domitian, Commodus, and Elagabalus — is however a retroactive speculation premised on a decidedly modern view of human nature and individual psychology. This modern view did not start to develop until the Late Middle Ages, reaching full fruition in the Enlightenment and Romantic movement of the eighteenth and nineteenth centuries
