History of Europe
In 395 Theodosius I, who had made Christianity the official religion of the Roman Empire, would be the last emperor to preside over a united Roman Empire. The empire was split into two halves: the Western Roman Empire centred in Ravenna, and the Eastern Roman Empire (later to be referred to as the Byzantine Empire) centred in Constantinople. The Roman Empire was repeatedly attacked by Hunnic, Germanic, Slavic and other “barbarian” tribes (see: Migration Period), and in 476 finally the Western part fell to the Heruli chieftain Odoacer.
Ambrosius Aurelianus
In Valerio Massimo Manfredi's "The Last Legion", Aurelianus (here called "Aurelianus Ambrosius Ventidius") is a major character and is shown as one of the last loyal Romans, going to enormous lengths for his boy emperor Romulus Augustus, whose power has been wrested by the barbarian Odoacer. In this story, Romulus Augustus marries Igraine, and King Arthur is their son, and the sword of Julius Caesar becomes the legendary Excalibur in Britain. In the 2007 film version of the novel, he is played by Colin Firth and his name becomes "Aurelianus Caius Antonius". In both he is called "Aurelius" for short.
