2. Part 2: Total War

Larry Lamb reveals how the Roman Empire became the dominant power in the Mediterranean. Beginning his quest at the Roma Termini train station in central Rome, he learns how the city was attacked by the Gauls in the Battle of the Allia, fought roughly 400 years BC. This three-year conflict inflicted great losses and damage, and left the Romans believing that attack was the best form of defence.

3. Part 3: Death of a Hero

During the mid-second century BC, Rome was enjoying the spoils after defeating Carthage in the Third Punic War, with slaves, treasure and art pouring into the republic. Larry Lamb examines how not everyone was reaping the benefit and reveals that resentment was mounting as the gap widened between the poor and the privileged. The actor traces the journey of Tiberius Gracchus, a man from the elite ruling classes who eventually came to champion the cause of the common citizen farmer, and learns about the development of the hypocaust, Rome's famous central-heating system.

4. Part 4: Caesar

Larry Lamb concludes his exploration of the Roman Empire by looking at the life and career of Julius Caesar. The actor traces the story of the great man's extraordinary transformation from a bankrupt junior public official to the seemingly invincible general who conquered Gaul, through to his infamous assassination in a debating chamber. Along the way, Larry discovers that money was often at the heart of the decisions Caesar made.
