Slide: Geometry of the Flagellation He gets his clue from the dimensions of the painting; 58.4 cm (one braccio ) by 81.5 cm., giving the ratio of the sides = 1.40 ~ 2 1/2 . If we swing arc EB from A, we get a square ASED. Thus the width of the painting equals the diagonal of the square, verifying that the frame is a root-two rectangle. The diagonal AE of that square passes through the V, vanishing point of perspective. Further, in square ATVK we see that arc KT from A cuts the diagonal at Christ's head, F, halfway up the painting. Thus Christ's head is at the center of the original square ASED. The Tile patterns: Christ stands on a simple green circle, inscribed in a square. A case of squaring the circle? Kemp points out that the tile pattern

Unformatted text preview: inside the praetorium is complex, and based on the diagonal of a square, an irrational number such as found in the proportions of the frame. The tile pattern outside the praetorium is simple squares, in an Albertian grid, and there is no apparent correlation between them. This seems to create two separate zones : the space inside, occupied by Christ, and the more mundane world outside. Deliberate? Kemp says that for someone as subtle as Piero, this is not impossible. Further, the tiles inside the praetorium form an octagonal pattern. Recall from our unit on number symbolism that the octagon suggests resurrection and baptism, because Christ rose from the tomb eight days after entering Jerusalem....
