Transverse rib
A transverse rib (French: arc doubleau) is a term in architecture given to the rib structure of a rib vault that spans the breadth of a vaulted ceiling, such as that of a church nave, dividing it into bays. In Roman architecture Transverse ribs were often sunk in or below the barrel vault of thermae, as in the piscina at Baiae and the so-called Baths of Diana (Nymphaeum) at Nîmes. In the Romanesque and Gothic styles of church architecture, Transverse ribs are principal feature of the vault, so much so that Scott[1] termed it the "master rib".[2]
