The term Norman may have originated with eighteenth-century antiquarians, but its usage in a sequence of styles has been attributed to Thomas Rickman in his 1817 work "An Attempt to Discriminate the Styles of English Architecture from the Conquest to the Reformation". In this work he used the labels "Norman, Early English, Decorated, and Perpendicular". The more inclusive term "romanesque" was used of the Romance languages in English by 1715, and was applied to architecture of the eleventh and twelfth centuries from 1819.
