Glossary

Rubbed brickwork
Soft brick sawn roughly, then rubbed to a precise (gauged) surface. Mostly used for door or window openings. Also called gauged brickwork.
Rubble
Masonry whose stones are wholly or partly in a rough state. Coursed: coursed stones with rough faces. Random: uncoursed stones in a random pattern. Snecked: with courses broken by smaller stones (snecks).
Rundbogenstil
(German, lit. round-arched style): A simplified style developed in early 19th-century Germany, drawing on Early Christian, Byzantine, Romanesque and early Renaissance precedents; sometimes echoed in British 19th-century buildings.
Rustication
Exaggerated treatment of masonry to give an effect of strength. The joints are usually recessed, by V-section chamfering or square-section channelling (channelled rustication). Banded rustication has only the horizontal joints emphasized. The faces may be flat, but can be diamond-faced, like shallow pyramids, vermiculated, with a stylized texture like worm-casts, and glacial, like icicles or stalactites (also called frost-work). Rusticated columns may have their shafts treated in any of these ways.
Rybats
(Scots): Dressed stones at the edges of an opening. Also called margins.
