BBC - The Dark Ages An Age of Light (2012)

Waldemar Januszczak challenges the prevailing wisdom that civilisation stopped after the fall of the Roman Empire and argues that the Dark Ages were actually a time of great artistic achievement, with new ideas and religions provoking new artistic adventures. He embarks on a fascinating trip across Europe, Africa and Asia, visits the world's most famous collections and discovers hidden artistic gems, all to prove that the Dark Ages were actually an 'Age of Light'.

Part 4: The Men of the North
In the final episode, Waldemar looks towards the north of Europe. The Carolingians saw themselves as successors to Rome, reflected in their art. Elsewhere, the Vikings were constructing long ships with intricate decoration and marking their territory with powerful rune stones. And on the British Isles, the Irish and Anglo-Saxons were creating unique works of manuscript illumination and remarkable jewellery.
