Elagabal is the name of the Syrian sun god whose high priest Varius was, at the same time as Roman emperor, AD 218-222. Because of this connexion, Varius was misnamed Heliogabalus or Elagabalus long after his death. Second in the series Varian Studies, this book discusses Elagabal's architectural and sculptural artefacts in Rome. These are represented by the Palatine site of the Varian Temple of Elagabal in Rome, and by relief sculpture on column capitals found in the Roman Forum, showing Elagabal with other deities, in a scene of sacrifice here reconstructed as Elagabal's Idyll. The Varian Temple of Elagabal in Rome confirms on topographical grounds an hypothesis regarding the site of that temple on the Palatine, concurring with current archaeological opinion based on other grounds. It also shows that the site in question has definite astronomical implications. Elagabal's Idyll gives a full account of scholarship concerning the three column capitals and the debate about their origin and function. It then goes on to analyse the iconography of one of them in order to explore the cosmology, theology and ritual of the cult of Elagabal.
