"What would you do if you were king of the world and could have everything and anything you wanted? Gaius Caligula was - and he did. This is the story of Caligula's four year rule from his point of view - seeing things the way he saw them, trying to walk a path between paranoia and the flattery of those who intended to use his madness to further their own ends; trying to live up to the myth of his dead father Germanicus; trying to resist the absolute power that threatened to let loose absolute madness. Suetonius tells the story from the inside - Caligula not as monster but as victim and, in the end, claiming our sympathy as well as our horror." - radiolisings.co.uk
