EPITITHEDAS.—A term applied by some writers, by way of distinction, to the cymatium on the sloping or _raking_ cornices of a pediment, which _superimposed_ moulding (as its name implies) was frequently largely developed, and enriched with an ornamental pattern. FENESTRATION, termed by the Germans _Fenster-architektur_, is, in contradistinction from columniation, the system of construction and mode of design marked by windows. Fenestration and Columniation are so far antagonistic and irreconcileable, that fenestration either interferes with the effect aimed at by columniation with insulated columns, as in a portico or colonnade, or reduces it, as is the case with an engaged Order, to something quite secondary and merely decorative. Astylar and Fenestrated ought, therefore, to be merely convertible terms; but as they are not, we may be allowed to invent that of _columnar-fenestrated_, to denote that mode of composition which unites fenestration with the _semblance_, at least, of the other. Employed as a collective term, Fenestration serves to express the character of a building or design with regard to the windows generally: thus we say, the Fenestration is excellent, or the contrary,—ornate or meagre,—well arranged or too crowded,—which last circumstance is a very common fault, and is destructive both of grandeur and of repose. _Si quæris exemplum, circumspice._ FILLET.—Any narrow flat moulding or surface is so termed. Fillets are used either to separate or finish other mouldings. The intervals or spaces between the flutes on the shaft of a column are also called fillets, although not actual members, but merely the surface left between the hollowed channels or flutes themselves. FLUTING.—The collective term for the channels cut on the shafts of columns. Hitherto this has been restricted to little more than two modes, viz. with arrises or sharp ridges, as in the Doric Order (p. 17), or with fillets. A different mode of _striating_ the shafts of columns is described at page 39, and many others might easily be devised.
