The York Glaziers Trust undertakes all work associated with the care and protection of York Minster's 128 windows, which contain the largest and most diverse collection of historic stained-glass in Britain.
Every five years the Minster's windows are inspected and their condition is monitored. Priorities for repair and conservation are identified in consultation with the Dean and Chapter, the Surveyor of the Fabric and the York Minster Fund and a programme of work is planned. Occasionally the Trust is called in to undertake emergency repairs arising from accident or vandalism.
A large part of the Trust's current work is on the Great East Window, the largest single expanse of medieval stained glass in Britain and the master-piece of Coventry glazier John Thornton. It was commissioned in 1405 and completed by 1408 with York Minster's Chapter paying £56 for the work, according to information gleaned from 17th-century copies of the medieval contract.
The window is a work of immense ambition, depicting the beginning and end of all things, from the creation of the world as described in the book of Genesis, to the events that will presage the end of the world and the second coming of Christ as told in the visionary Book of Revelation, know in the Middle Ages as the Apocalypse. As part of the Minster's York Minster Revealed project, the Apocalypse scenes and sections of the Tracery from this extraordinary window are being studied, conserved and returned with a revolutionary protective glazing that will secure the future of the 600-year-old stained-glass for many generations to come.
