Sometime between the years 69 and 75, the Roman historian Gaius Suetonius Tranquilius was born. Better known by "Suetonius," he belonged to the equestrian order and lived in the early Imperial era. He wrote many things, but the most important of his works that have survived is called De Vita Caesarum, and it is a compilation of the biographies of twelve successive Roman rulers, from Julius Caesar to Domitian. In his other works, he writes of the daily life of a Roman citizen, oratory, politics, and the lives of famous poets, historians, and grammarians. Many of these books have been lost, though some survived. He died sometime after 130.
