No. 134. Forms of Mouldings.
Mouldings are an important factor in effect, not only in Architecture, but in structural form generally. In flat decoration they have to some extent their corollary in borders, the proportionate widths of which are governed by similar rules.
Of mouldings with curved profiles there are only six distinct forms, though the individual character of these curves is subject to great variation in treatment.
Purpose
As suggested, mouldings have a distinct purpose, are, in fact, functional features, and may be defined as Sheltering or Crowning, Bracketing or Supporting, and Binding.
In any composition where they may be necessary these functions should be taken into consideration.
The profiles should always be concise whether the character of the curve be refined or robust.
In classic architecture the relative proportions of the mouldings to the other features are defined, and these proportions will be found useful in other than purely architectural design.
