The book by the French scholar J.-P. Nerodo is devoted to the heir and successor of Gaius Julius Caesar—the best-known ruler, the creator of the Roman Empire—Princess Augusta (63 BC–14 AD). Its distinguishing feature is that the author aims to reveal not the image of a politician, but the secret of the identity of this mysterious person. He strips away the mask that the first emperor wore all his life, and does it with pure French ease—fascinating and free. Nerodo studied in depth all the sources related to the life of Gaius Octavius—Caesar Octavian—Augustus, and looked into the inner world of a man who sequentially had three names.
