Although in the See also:Roman vault the rib played an important See also:element in its construction, it was generally hidden in the thickness of the vault and was made subservient to its geometrical surfaces

The See also:Gothic masons, on the other See also:hand, reversed the See also:process, and not only made the vaulting See also:surface ' subservient to the rib, but by See also:mouldings rendered the latter a highly decorative feature
.
The See also:principal ribs are the transverse (arc doubleau), the See also:diagonal (arc See also:ogive) and the See also:wall rib (See also:formeret)
.
Those of less importance are the intermediate, the See also:ridge and lierne ribs

.
(See VAULT.) A lierne rib (the See also:term is borrowed from the See also:French) is 'a See also:short rib, introduced into the vaulting in the See also:Early Perpendicular See also:period, which coupled together the transverse and intermediate ribs; in the later period the " lierne " rib becomes one of the See also:chief features of the " stella " vault (see further VAULT)
