The Roman Deification of Julius Caesar - Divus Julius

"Julius Caesar was the first historical Roman to be officially deified. He was posthumously granted the title Divus Iulius or Divus Julius (the divine Julius or the deified Julius) by decree of the Roman Senate on 1 January 42 BC. Though his temple was not dedicated until after his death, he may have received divine honours during his lifetime:[100] and shortly before his assassination, Mark Antony had been appointed as his flamen (priest).[101] Both Octavian and Mark Antony promoted the cult of Divus Iulius. After the death of Antony, Octavian, as the adoptive son of Caesar, assumed the title of Divi Filius (son of a god)." - http://en.wikipedia.org/wiki/Julius_Caesar
