RIB (from 0. Eng. ribb; the word appears' in many See also:Teutonic See also:languages, cf. Ger. Rippe, Swed. reb)  , in See also:anatomy, the See also:primary meaning, one of the See also:series of elastic arched bones (costae) which See also:form the casing or framework of the See also:thorax (see See also:SKELETON: Axial) . The word is in meaning transferred to many See also:objects resembling a See also:rib in shape or See also:function . In See also:architecture, it is thus used of the See also:arches of See also:stone which in See also:medieval See also:work constitute the skeleton of the vault, and carry the See also:shell or See also:web . 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 . The ridge-rib is one first introduced into the vault to resist the thrust of the intermediate ribs between the wall and diagonal ribs; it also served to See also:mark the junction of the filling-in or web of vaults in those cases where the courses dipped toward the diagonal rib . (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) .
