Tony Sullivan lives in South East London with his wife and three children. His first book, King Arthur: Man or Myth? was published in 2020. Three further books followed in 2022: The Battles of King Arthur investigating the famous battle list from the Historia Brittonum; The Real Gladiator, looking at the historical reality behind the 2000 film; and The Roman King Arthur?: Lucius Artorius Castus, which dismantles the Artorius-Arthur theory and places this historical Roman officer in the reigns of Severus and Caracalla.
