this radiation contains a chemicalfingerprint, from which the researchers worked out its age. we ve been working on this detective story for some time, putting all the pieces in place, and then we finally get an answer, something new, that brings together science and art into one story. it s fantastic. these are all stories that were recorded at the time they happened here. the discovery has astonished leonie seliger, who looks after the stained glass windows here. she believes the panels could go back to the mid 1100s, and were in place during major historical event of the cathedral, including the assassination of the then archbishop thomas becket, who features in many of these windows. they would have witnessed the murder of thomas becket. henry ii coming on his knees begging for forgiveness. they would have witnessed the conflagration of the fire that devoured the cathedral in 1174.

that some of these panels were made earlier than the others, because they re different in style. now, using a new technique, scientists have confirmed that not only are they much older, but they may well be among the oldest in the world. it s only come to light now because of this device, called a windowliser. it may not look like much, but it was developed by scientists to be used on location without damaging the glass. it shines a beam onto the surface, which causes the material inside to radiate. this radiation contains a chemicalfingerprint, from which the researchers worked out its age. we ve been working on this detective story for some time, putting all the pieces in place, and then we finally get an answer, something new, that brings together science and art into one story. it s fantastic. these are all stories that were recorded at the time they happened here. the discovery has astonished leonie seliger, who looks after the stained glass windows here.
