[2] In September 1440 he was named as King's Glazier, a post which gave him the use of the "glasiers logge" or "shedde" in Westminster Palace, a gown at Christmas,[3] and wages of 12 pence a day.
[2] The windows for the Beauchamp Chapel were Prudde's best-documented and now most acclaimed work; it is also believed to have been the most expensive glazing project in 15th-century England.
[2] This contract makes it clear that Prudde was to work from small-scale designs provided for him, from which larger copies would need to be made before being recopied onto glass.
[10][1] He used this technique on a larger scale than can be found in any other English glass of the period, giving the Beauchamp Chapel windows, according to the art historian Richard Marks, "a glittering effect unmatched within the British Isles".
[2] St Leonard's Church, Bledington, Gloucestershire has windows containing the pieced together remains of medieval painted glass, including some complete panels, which have been tentatively attributed to Prudde.
