 Before the decisive engagement, Licinius allegedly had a vision in which an angel recited him a generic prayer that could be adopted by all cults and which Licinius then repeated to his soldiers.On 30 April 313, the two armies clashed at the Battle of Tzirallum, and in the ensuing battle Daia's forces were crushed.Ridding himself of the imperial purple and dressing like a slave, Daia fled to Nicomedia.
