This is the first biography of Hadrian since 1923. Hadrian's reign (AD 117-138) was a watershed in the history of the Roman Empire. Hadrian abandoned his predecessor Trajan's eastern conquests - Mesopotamia and Armenia - trimmed down the lands beyond the lower Danube, and constructed new demarcation lines in Germany, North Africa, and most famously Hadrian's Wall in Britain, to delimit the empire. No comprehensive account of Hadrian's life and reign has been attempted for over seventy years. In Hadrian: The Restless Emperor , Anthony Birley brings together the new evidence from inscriptions and papyri, and up to date and in-depth examination of the work of other scholars on aspects of Hadrian's reign and policies such as the Jewish war, the coinage, Hadrian's building programme in Rome, Athens and Tivoli, and his relationship with his favourite, Antinous, to provide a thorough and fascinating account of the private and public life of a man who, though hated when he died, left an indelible mark on the Roman Empire.
