Gold fob seals, Sheffield silver, Mesolithic stone tools - these were some of the discoveries detailed in the 28 papers, books and pamphlets published by a soldier turned archaeologist who began looking at what you might find in the soil in the middle of a World War I battlefield.

Dr Seren Griffiths teaches at Manchester Metropolitan University and is involved in a project to use new scientific dating techniques to write the first historical narrative for two thousand years of what was previously 'prehistoric' Neolithic and Bronze Age Britain and Ireland. She has also organised public events at the excavations she co- directs at Bryn Celli Ddu in North Wales and you can hear her talking about midsummer at a Neolithic monument in an episode of Free Thinking.
