THIS talk is the first of four in which Miss J- Eileen Power will carry on the story of Europe from the fall of the Roman Empire, where Mr. Norman Baynes left it, to the birth of Modern Europe, where Mr. Somervell will take it up. She will deal with the mediaeval period, which was not merely a bridge between the ancient and the modern world, but had a distinct and notable civilization of its own; starting today with tho Dark Ages and their unifying forces - the Catholic Church, tho Frankish kingdom (which became the Holy Roman Empire) and the feudal system.
