[...] at last [...] it occurred to some philosopher or mechanic [...] that by arranging small wedge-shaped stones or other materials in a semicircular form, a sort of curved lintel could be obtained, which, though composed of many distinct parts, could be stretched from pier to pier, or from pillar to pillar [...]. [...] There have been, in some stone constructions, what may be regarded as intermediate steps between the lintel and the arch.
The arch can be called a curved lintel.
