Gaius Julius Caesar (12 July 100 BC – 15 March 44 BC) was a Roman general and statesman who played a critical role in the events that led to the demise of the Roman Republic and the rise of the Roman Empire.
Gaius Suetonius Tranquillus commonly known as Suetonius (c. AD 69 – after AD 122) was a Roman historian who wrote during the early Imperial era of the Roman Empire. His most important surviving work is a set of biographies of twelve successive Roman rulers, from Julius Caesar to Domitian, entitled De vita Caesarum. Other works by Suetonius concern the daily life of Rome, politics, oratory, and the lives of famous writers, including poets, historians, and grammarians. A few of these books have partially survived, but many have been lost.
