PERPENDICULAR Little proof is needed of how greatly the glazier depended upon the architect, or of how necessary and proper it was that his glazing should harmonise with the prevailing architectural style. The period we are about to study affords a striking example of this subserviency of the window to the building it lights. In no country can there be found a school whose glass was so dominated by its architecture as was that of the Perpendicular in England. This Perpendicular style never crossed the Channel, for the French Gothic of that time, instead of becoming stiff and regular, grew more flamboyant and elaborated. Another marked difference is that all the time the English were softening their tints and striving for a silvery sheet of low tones (Great Malvern, &c.), the fifteenth century French were, on the contrary, using stronger and more varied colours than during the century before. To such excellence of delicate drawing and tints did the English attain in their Perpendicular windows that it may safely be said that in those respects they were never surpassed elsewhere. This is particularly noticeable at Ross and Cirencester. An opportunity to compare the French with the English glass of that time is afforded by the fact that the French windows of the Beauchamp Chapel at Warwick will be visited between the distinctively English ones of Great Malvern and York. This Warwick glass was brought from France because the contract exacted "Glasse from beyond the Seas," and we at once notice the strong hues, which differ so markedly from the then prevailing English ones. Nothing could be more convenient than the way in which these particular windows enable us to differentiate between contemporary glass on opposite sides of the Channel.
