Caligula was the third Roman emperor, ruling from AD 37 to 41. Ancient sources portray a reign that began with popularity but became associated with autocracy, court terror, financial pressure and conflict with the Senate before his assassination by guards.
In Margaret George’s The Confessions of Young Nero, the narrative follows Lucius Domitius Ahenobarbus, the future emperor Nero, from his endangered childhood under Caligula to the opening years of his own reign.
In non-fiction, Caligula is discussed in Lindsay Powell’s Germanicus, L. J. Trafford’s Ancient Rome’s Worst Emperors, Lindsay Powell’s Tiberius, Mary Beard’s Twelve Caesars, and Mary Beard’s Emperor of Rome. In Lindsay Powell’s Germanicus, the final chapters examine the persecution of Germanicus’s widow and children under Tiberius and Sejanus, and the survival of his public image through Caligula, Claudius and later Roman memory.
