In this final episode, Professor Alice Roberts is back on the train and learning more about the Ancient Greek culture that thrived in Türkiye over 2000 years ago. From the Aegean port of Kusadasi, Alice goes to the spectacular and beautifully preserved city of Ephesus. Later, she encounters an important historic rock carving, from an empire before the Greeks, that's recently been vandalised. Alice visits an old friend at the acropolis of Pergamon, then scrutinises an expert on Troy to test the veracity of the ancient stories of Homer in The Iliad, as she completes her own personal odyssey.
