Elagabalus /ˌɛləˈɡæbə.ləs/, Aelagabalus, or Heliogabalus /ˌhiːliəˈɡæbə.ləs/ is a Syro-Roman sun god. Although there were many variations of the name, the god was consistently referred to as Elagabalus in Roman coins and inscriptions from AD 218 on, during the reign of emperor Elagabalus.
Elagabalus was initially venerated at Emesa in Syria. The name is the Latinised form of the Semitic Ilāh hag-Gabal, which derives from Ilāh "god" and gabal "mountain" (compare Arabic: جبل jabal), resulting in "the God of the Mountain", the Emesene manifestation of the deity. The cult of the deity spread to other parts of the Roman Empire in the second century. For example, a dedication has been found as far away as Woerden, in the modern-day Netherlands.
