Ridge rib
Also called ridge ribs
A rib running along the crown of a vault, longitudinally or transversely, linking the bosses.
See also: Tierceron
Rules that use the word
Tiercerons: more ribs from each springer. Add to the diagonal ribs further ribs (tiercerons) that rise from the same springers to points on the ridge rib, so that each springer sends up a sheaf of ribs and the vault reads as a palm.
Where it appears in the book
