Nicholas Jubber’s Epic Continent is at once a travelogue, set very much in the Europe of the present, and a quest for the literary past as it survives today. His modern odyssey, starting at the ancient site of Troy in Turkey, just off the edge of Europe, and ending in Iceland in the very far northwest, is not without its moments of stress. On Cape Tanairon in Greece, allegedly the site where Odysseus descended into Hades, he puts down his backpack to get into the sea cave said to be the entrance. He leaves it by a slant of limestone so he can find it again. But when he comes out, he realises that there are a hundred such outcrops. He never finds his backpack, and the loss is serious (if not on an epic level) because it contains his serotonin pills.
