Gaius Cornelius Tacitus, commonly known as Tacitus (born c. 56 – c. 120 AD), was a Roman historian and senator who authored several significant works that contribute vastly to our understanding of Roman history and governmental systems. Tacitus is known for his incisive analysis and penetrating insights into the Roman Empire's political and social issues. His writing evinced a remarkable understanding of human character and the flow of history, often highlighting the interplay between fate and the individual's actions. Among his essential works is 'The Life and Death of Julius Agricola' ('De vita et moribus Iulii Agricolae'), a biography of his father-in-law, which also serves as a source of British history and a depiction of Roman Britain. This book, like many of his other works, reflects Tacitus' literary style characterized by brevity and piercing conciseness, that has proven influential on both contemporary and subsequent historiography. His other notable works such as 'Annals' and 'Histories' offer detailed accounts of the Roman Empire from the death of Augustus to the end of the Flavian dynasty. Through his critical and often cynical portrayal of the vices of imperial Rome, Tacitus has earned a reputation as one of antiquity's greatest historians.
