France's later works include L'Île des Pingouins (Penguin Island, 1908) which satirizes human nature by depicting the transformation of penguins into humans – after the animals have been baptized by mistake by the nearsighted Abbot Mael. It is a satirical history of France, starting in Medieval times, going on to the writer's own time with special attention to the Dreyfus Affair and concluding with a dystopian Future. Les dieux ont soif (The Gods Are Athirst, 1912) is a novel, set in Paris during the French Revolution, about a true-believing follower of Maximilien Robespierre and his contribution to the bloody events of the Reign of Terror of 1793–94. It is a wake-up call against political and ideological fanaticism and explores various other philosophical approaches to the events of the time. La Revolte des Anges (Revolt of the Angels, 1914) is often considered Anatole France's most profound novel. Loosely based on the Christian understanding of the War in Heaven, it tells the story of Arcade, the guardian angel of Maurice d'Esparvieu. Arcade falls in love, joins the revolutionary movement of angels, and towards the end realizes that the overthrow of God is meaningless unless "in ourselves and in ourselves alone we attack and destroy Ialdabaoth."
