Published by Penguin for more than sixty years, the author and scholar Robert Graves wrote two of the greatest historical novels of the twentieth century: I Claudius and Claudius the God. Written as Claudius' autobiography, they follow his progress from a stammering figure of fun to the ruler of the Roman Empire. Here, in extracts from both books, he describes the glory and decadence of the mad Emperor Caligula's reign - an age of wild debauchery and whimsical cruelty.
