The blue, sloping Intrado

"Up to the twelfth century the windows of the Romanesque churches had small openings for light, a sloping intrados, and an inclined sill. Originally without decoration, they later received a framework, that is, they were surrounded by a border of slender shafts as by a frame. The most frequent and most artistic form is the combination of the simple frame and the truss-frame, from which spring the most varied combinations, as sometimes the simple frame encloses a truss-frame, or the reverse, or sometimes two truss-frames are combined with each other."

Sam Renseiw combined some frames for a piece of footage, probably transcending time and space a tad, kind of blurrry. View it here or click on the blue sloping intrado above (patafilm 117, 01'23'', 4.2 MB, mov/quicktime) / relinked 02.10.15
