[M.67L] [M.67] [diagram] No 47 Ca Giustiniani 67 No 47.Fig 1. Details of Traceried window in palace of the young Foscari. A archivolt with tracery: B tracery bar: The recess above the dentil at top is, I think intended to be filled with marble; it exists in nearly all the windows of this palace: showing the general system very nicely; Masonry asquarerectangle is left in the bricks; this is walled with marble dentil edge: forming the Sq; then the archivolt and pilaster are introduced independently, vide opposite. In these windows the recess seen in section goes all round and the finial of the window is worked roughly back to it - only faced with leafage; as if marble were to be put in. It is occupied now with canvass painted in imitation of it Traceries. C: Tracery bar, drawn larger with cusp: D tracery bar without cusp, as at point of arch, the arch thus leaving a fillet between it and the bar: not meeting it as at Danielis, Now, it is most singular that the whole window is not worked with this section. In the two small 4foils near top, there would have been no penetration large enough for effect; and the tracery bars have their sides to those 4foils of the section E: whose vertical depth a b of course equals that of the other side of the bar, or a2 b2 in B: The cusp in E is unfilleted; and the foil leaves no fillet at its point, but reaches the point c. as seen
