The historian and classicist goes Greek island-hopping to explore their history from the time of the Ancients to the present day. In Santorini, she visits a Minoan city preserved in time by one of the most violent volcanic eruptions in history. Bettany's next port of call is Naxos, where in an abandoned marble quarry, she finds a genuinely monumental statue of the god that has lain there for thousands of years, before heading to a taverna to take part in some local festivities. The presenter later arrives in Sifnos, where long-distance communications were mastered millennia before telegrams or telephones.
