The seven lamps of architecture
John Ruskin's 1907 architectural treatise The Seven Lamps of Architecture, published in London and New York by Routledge and Dutton, offers plates of medieval Gothic and Romanesque ornament for students of building. The plates are measured line engravings and etchings of carved arches, tracery, rose windows, capitals and mouldings, drawn close enough that a designer can read each chisel cut and foliage curl. They suit pattern work built on pointed arches, quatrefoils and rosettes, and stone-carved ornament.
