To really understand Rome, you must understand its people - or the mob, as they were known in ancient times. As Giorgio Locatelli and Andrew Graham-Dixon explore Italy's iconic capital, they are in search of the generations of ordinary Romans who have left their mark on the city's culture and gastronomy.

Colin Stafford-Johnson begins his Atlantic journey exploring the ancient ruins and wildlife of the Skellig Rocks - stormbound ocean pinnacles off the south western corner of Ireland, where early Christian monks built a monastery on the summit almost 1,500 years ago. His journey ends in Clew Bay, an iconic inlet halfway up Ireland's west coast and the place Colin chose to make his home.
A hundred miles south of Cairo a stretch of the Nile was once considered Egypt's main highway, used by Cleopatra to travel the country. More than 2,000 years after her, Bettany visits a vast desert catacomb where tens of thousands of mummified animals were once left as an offering. Further upstream, there is a chance to swim in the Nile, and look inside the tombs where Tutankhamen's discoverer, Howard Carter, first got hooked on Egypt. Bettany explores the longest tomb yet found, before heading to the Dendera temple, where Cleopatra herself may have once wowed her lover Julius Caesar.
The odyssey continues as Colin Stafford-Johnson completes his journey along Ireland's Atlantic rim. Exploring the wildlife and mountains around his home inlet of Clew Bay, Colin then heads north for Donegal - golden eagle country - before reaching the island's northern tip and turning east along the coast of Northern Ireland.
The third leg takes him from the illegally annexed peninsula of Crimea to the historic Baltic city of St Petersburg. Crimea is part of neighbouring Ukraine but was annexed by Russia in 2014. President Putin's government is investing heavily in the illegally occupied territory - building a huge bridge linking Crimea to Russia. Simon meets the eccentric and fearless owner of a safari park who likes to get up close and personal with his pride of lions. The owner is struggling to get water to his park after a canal that supplied much of Crimea's water was shut off by the Ukraine. And it is not just the lions that are affected - the diminishing water supplies are now beginning to threaten a humanitarian crisis.
