This exhibition is on at the Sam Fogg Gallery in Clifton St, London, until 25 October. The gallery website describes it as follows:

‘the first exhibition of its type to be held in over 10 years, and consists of 55 stained-glass panels brought together over the course of the last two decades. They were all created in France, the Netherlands and the German-speaking lands across a period spanning some three centuries. … We have been very fortunate to find several intact window panels, which beautifully demonstrate the ingenuity with which medieval painters and glaziers, working in collaboration, negotiated relationships of colour and the properties and problems inherent to the medium. Most often however, medieval stained glass survives in the form of isolated fragments … In this exhibition alone are long-dispersed fragments from some of the medieval period’s greatest glazing programs, including the rich churches of Rouen, the Sainte-Chapelle at Dijon, the abbeys and cloisters of the Rhine Valley, and the royal foundations of Paris and the Île-de-France. Displaced from windows many metres above our heads and brought down to eye level, we can now appreciate them as remarkable and sensitive works of art that, at their best, rival even the greatest paintings of their age.’
