All roads lead to Rome, so it was inevitable James would end up in Italy's magnificent capital. But it's not just Romans and ruins, James also goes on a bus, meets another version of himself, and looks at something too small to see.

James tests his Renaissance man credentials with a spot of art, science, and alchemy in Florence. Emilia-Romagna see the worlds of fast-moving cars and slow-aging cheese, before James ends up in a town that feels strangely familiar.

Size matters, as James visits the vast marble quarries of Carrara and the massive Genoa port. Then it's to the elusive, as James searches for a semblance of peace in the face of killer robots, and a decent cup of tea in Turin.

In Milan, James submits to a wardrobe update, tries his hand at some exquisite craftsmanship - and bids goodbye to an old friend. Next stop: Venice, by land, air, and lagoon, while in the Dolomites James finds the darker side of Christmas.
