At the time the Cathedral did not have its own glaziers department and the conservation was carried out in Kings Langley, Hertfordshire. The glass was duly returned but had to remain in store until the work on the Dean’s eye window had been completed.
And so when all the work was done on the Dean’s Eye, the Masons’ Window, together with its sister window, the Musicians window (also financed by the friends) was re-installed in its proper place.
The glass is 13/14th century and is thought to have come from the windows in the Angel Choir. Surmounted by a pair of compasses, the window comprises a series of rectangular panels of six-pointed stars made by two interlocking triangles. The design is completed by quatre-foil flowers on cross hatches.
