Hierocles (Greek: Ἱεροκλῆς, late 2nd century – 222 AD) was a favourite and lover of the Roman Emperor Elagabalus.
The Emperor made him his lover and husband and, as a consequence, Hierocles was alleged to have gained significant political influence.
Hierocles banished the Emperor's other lover, athlete Aurelius Zoticus, and inflicted physical violence upon Elagabalus when the latter was unfaithful.
Allegedly, Elagabalus' partiality towards Hierocles, coupled with his eccentricities, were the principal reasons he lost the support of the Praetorian Guard, which led to his death.
When the Emperor fell from power in 222, and was assassinated by the Praetorian Guard, Hierocles was executed, along with other members of Elagabalus' court.
