Athens, Alexandria, Tikal and Rome: these legendary cities are some of the world's most famous archaeological sites. And yet, they still have not revealed all their secrets. The ambition of this series is to resuscitate the first megalopolises of universal history.
In the first episode, the extraordinary city of Athens, the richest and most powerful in all of ancient Greece. The film leads us in the footprints of a nation of extraordinary builders, thinkers, and inventors of incredible machines.

Dr Michael Scott journeys to Athens to discover that from the very start the theatre was about more than just entertainment - it was a reaction to real events, it was a driving force in history and it was deeply connected to Athenian democracy. In fact, the story of theatre is the story of Athens.

Dr Michael Scott looks at the dramatic decline of Athens and the remarkable triumph and transformation of theatre. During the 4th century BC Athens would lose its Empire, its influence and even its democracy. But theatre, that most Athenian of inventions, would thrive, spreading throughout the Greek world and beyond and giving rise to a new kind of comedy, one so popular and prevalent that it is still at the heart of our comedy today.

Dr Michael Scott examines the vital role played by the Romans in the preservation of Greek drama and in the history of theatre.

In 1901, a group of divers excavating an ancient Roman shipwreck near the island of Antikythera, off the southern coast of Greece, found a mysterious object - a lump of calcified stone that contained within it several gearwheels welded together after years under the sea. The 2,000-year-old object, no bigger than a modern laptop, is now regarded as the world's oldest computer, devised to predict solar eclipses and, according to recent findings, calculate the timing of the ancient Olympics. Following the efforts of an international team of scientists, the mysteries of the Antikythera Mechanism are uncovered, revealing surprising and awe-inspiring details of the object that continues to mystify

Andrew Marr tells the story of the first empires which laid the foundations for the modern world. From the Assyrians to Alexander the Great, conquerors rampaged across the Middle East and vicious wars were fought all the way from China to the Mediterranean. But this time of chaos and destruction also brought enormous progress and inspired human development. In the Middle East, the Phoenicians invented the alphabet, and one of the most powerful ideas in world history emerged: the belief in just one God. In India, the Buddha offered a radical alternative to empire building - a way of living that had no place for violence or hierarchy and was open to everyone. Great thinkers from Socrates to Confucius proposed new ideas about how to rule more wisely and live in a better society. And in Greece, democracy was born - the greatest political experiment of all.
