Heliogabalus was Roman emperor from 218 to 222. A member of the Severan dynasty, he was Syrian, the second son of Julia Soaemias and Sextus Varius Marcellus. In his early youth he served the god Heliogabalus as a priest in Emesa, the hometown of his mother's family. As a private citizen, he was probably named Sextus Varius Avitus Bassianus. Upon becoming emperor he took the name Marcus Aurelius Antoninus Augustus. He was called Heliogabalus only after his death.
