Ireland and Scotland's long tradition of metal-strung harps died out two centuries ago, but a number of these iconic instruments survive. With the help of modern technology, their historical craftsmanship is being rediscovered for a new generation of harp makers. In this presentation we'll explore these harps inside and out with state-of-the-art imaging. We'll see hidden workmanship and repairs, reveal lost decorations, find clues to their histories, and see the results of radiocarbon dating one of the oldest European harps!
