Book I
Paterculus begins his history with the events following the Trojan War. He explores how the Roman Empire has become more of a Mediterranean empire than purely Roman, which realization holds implications for the governing of the people. The Median empire rises to power. Carthage is founded. With the founding of Rome, Paterculus emphasizes the ingenuity of the Roman people. He explains the Olympics in detail, praising the prowess of the noble competitors. Next he covers the various expansions of the empire -- Macedonia, Syria, Egypt -- and the establishment of colonies. In a discussion of the Punic Wars, Paterculus recalls once more the valor of individual soldiers, who suffered immensely from the indiscretions of their commanders.
Book II
After the city of Carthage breaks from Rome, a series of defeats characterizes the reign of Tiberius. The Numantine Wars keep Roman authorities occupied, leading to a renewed emphasis upon oration in the Senate and among the privileged populace. When Julius Caesar presides over the Civil War successfully, he achieves enough fame and favor to appoint himself emperor, seizing total control of the empire, until he's assassinated. Octavian, his adopted son, defeats Mark Antony for control of the state. Brutus and Cassius commit suicide. Next a series of wars occurs. In the midst of various conflicts, Mark Antony marries Cleopatra and has children with her. She, however, has become the powerful ruler of Egypt and poses a threat to Octavian, who threatens her children and exiles her to Alexandria. Together she and Mark Antony commit suicide, leaving Octavian to his solitary satisfaction.
Tiberius, as commander, leads another long succession of conflicts. He almost single-handedly stops the Pannonian and Dalmatian revolts, preserving the unity of the empire. He's become known as a harsh man, but he becomes emperor. After achieving much acclaim during his lifetime, Tiberius appoints Augustus as his heir. Finally Paterculus concludes with prayers for the prosperity and virility of Rome and the preservation of the emperor.
