And in one respect it's not quite erm as straightforward as I've made it appear, and perhaps after all I'm not wrong in making the claim I did, because E P Thompson, the historian, erm was the person who really made the discovery in the first place, and it came about because he had been interested in the possible links between the Muddletonians and Blake, and this led him to ask questions which, in a roundabout way, led to the discovery of the archive.
