VAULT 957 the arch was built in horizontal courses, up to about one-thirdof the height, and the rings above were inclined back at a slightangle, so that the bricks o( each ring, laid flatwise, adhered tillthe ring was completed, no centring of any kind being required;the vault thus formed was elliptic in section, arising from themethod of its construction. A similar system of constructionwas employed for the vault over the great hall at Ctesiphon,where the material employed was burnt bricks or tiles of greatdimensions, cemented with mortar; but the span was closeupon 8j ft., and the thickness of the vault was nearly 5 ft. atthe top, there being four rings of brickwork.
