On Vanbrugh's entrance facade to the kitchen court at Blenheim (59), disengaged columns, which frame the grand opening, are discordantly superimposed upon the windows that make up part of the regular rhythmic pattern behind. The same thing happens at Seaton Delaval (122), where the disengaged columns block some of the windows. The facade of St. Maclou, Rouen ( 123), is made up of layers of diagonal elements-traceried pediments, roofs, and buttresses-- differing in function though analogous in form. These juxtapositions are relatively separated in comparison with the facade of I1 Redentore ( 5 1 ) , whose ambiguously superimposed diagonals are broken pediments and exposed buttresses at the same time.
