Casting Lines

These are fragments of a plaster cast of an Oak alter piece, now in Schleswig Cathedral, by Hans Brüggermann, c 1514-1521, also in the plaster court at the Victoria and Albert Museum. While the oak carving is clearly very accomplished, the reason for posting these pictures is the attention to detail in setting the casting lines, where the various parts of the moulds meet. The lines mark out a topology of separation to avoid undercut and cast strange contours on the figures.
