This is a story, a true story which I always think are the best of stories. A Story of Ancient Rome. An Adventure Story, perhaps?
It is a story of two protagonists, Julius Caesar and Marcus Cato. They represented two opposing philosophies, both dedicated to the same end, the recovery of the health of the Roman Republic which was in their day unwell. Both men were fighters, Caesar on the battlefield where he was arguably the greatest tactician ever and certainly of his times, and plucked many a victory from the jaws of defeat. Cato fought in the Senate. There he opposed Caesar and everything he stood for. This is their story.
The book takes the form of alternating chapters written by each of the two protagonists, the Chapter Headings indicing who is writing and the main subject matter of the chapter.
