Some reviewers of "I, Claudius", the prefatory volume to "Claudius the God", suggested that in writing it I had merely consulted Tacitus's "Annals" and Suetonius's "Twelve Caesars", run them together, and expanded the result with my own "vigorous fancy." This was not so; nor is it the case here. Among the Classical writers who have been borrowed from in the composition of "Claudius the God" are Tacitus, Cassius Dio, Suetonius, Pliny, Varro, Valerius Maximus, Orosius, Frontinus, Strabo, Caesar, Columella, Plutarch, Josephus, Diodorus Siculus, Photius, Xiphilinus, Zonaras, Seneca, Petronius, Juvenal, Philo, Celsus, the authors of the "Acts of the Apostles" and of the pseudo-gospels of Nicodemus and St. James, and Claudius himself in his surviving letters and speeches.
