Groin; oblique intersection of two splayed vaults of the same spring

This is one of a large set of ruled surface models made by Fabre de Lagrange, in Paris, France, following designs introduced in the early 19th century. They illustrate surfaces which can be traced out in space by the movement of a straight line. This particular model shows a groin, an oblique intersection of two vaults of similar spacing.
