Tuscan Passage |
Moldings derive from the architectural orders
which were codified during the Renaissance as: Tuscan, Doric, Ionic,
Corinthian, and Composite.
Parallel of the Orders by Perrault |
The orders serve to organize or “order” the supporting
(columns) and supported (entablatures) structural elements of a building. This
ordering is given by the disposition of their component parts (moldings), their
character, and proportion. Thus, Tuscan and Doric orders are associated with masculinity,
the military, earth and strength. The Ionic, Corinthian, and Composite orders are
associated with femininity, lightness, rebirth and transcendence. There are many variations of these five basic
orders as each successive generation has expanded, altered, or modified and
adapted them to their time and circumstance.

While the orders have a base, a
middle, and a top all the different moldings that in turn, make up the base,
middle and top also have their own tri-partite system and the same repeats for
the sub-pieces within them. For example: columns have a base, a middle (shaft)
and a top (capital). The base in turn is composed of a plinth, a torus, and a
cincture; the capital, of the necking, echinus, and abacus. Entablatures have an architrave, a frieze, and a
cornice. Cornices in turn have a bed molding, a corona, and a cymatium…and so on and so forth.
All these sub-pieces are
made with concave, convex, flat, or compound shaped pieces that are what we
know as moldings. Their shapes have been codified for the past 2,000 years by
their geometrical forms. So, the concave moldings are called: cavetto and
scotia; the convex moldings are the ovolo and the torus; the flat moldings are the
fascia and the fillet; and the compound moldings are the cyma recta, the cyma
reversa, and the beak (see the chart below).
Sir William Chambers classified
moldings according to how they express their role or relative position in the
orders. There are some that support such as the ovolo or the echinus (which are
found in the column capital); those that crown the building such as the cavetto
or the cyma recta (found in the cornice); those that bind such as the torus or
the bead (found in the column base) and those that separate such as the scotia,
the conge or the beak. Chambers talks about their expressive qualities to show
the effect of gravity on the structure. John Wellborn
Root (of Burnham and Root) took this idea to an ultimate expressive form in the
Society for Savings Bank in Cleveland. Here the toruses at the bottom of the columns
look as if they are being squeezed, by the enormous weight of the building on
top, and the column capitals look like they are supporting this weight by
substituting the typical echinus of the column capital with rough-hewn stones.
The column shafts are exaggeratedly shortened thus emphasizing the tremendous
weight above.
When used in interiors, moldings are sometimes
modified in size by making them slender in proportion, as in the interior of Gunston
Hall in Virginia (1755-59). Sometimes moldings are omitted from their customary
place in a typical entablature. In Syon House, Middlesex, England (1760s),
Robert Adam omitted the architrave as the entablature overlaps the wall. By doing that he signaled that the wall is actually
doing the supporting and the frieze becomes more decorative; this is an
appropriate function for the frieze in an interior. In a similar move, Gunston
Hall, virtually eliminates the architrave as well.

There are proportional rules of thumb that can
be used to size a crown, an architrave or a base molding. These stem from the
proportions of the underlying order of a particular room. For instance if a
room is ordered by a Doric proportional system then its crown, architraves, and
room bases will be tend to be both simpler and chunkier than if the room is
ordered by a Corinthian system.
The room pictured above is in a house called
Wilton in Richmond, Virginia (1753). It is a good example of American Georgian.
The proportions of Georgian rooms tend to be less delicate than those of
Federal rooms such as the one pictured below in a house called Edgewater in Barrytown,
New York (c.1820).

So other than general historical scholarship why
is any of this relevant to the 21st century? The fact is that houses
are still being built following traditional paradigms because people like to
live in places that are familiar, that help them to recall where they came
from, and that are responsive to the climate and culture that they are built in. Most new houses in the US are built in what is generally considered a
traditional “style”. The problem with many newly built houses is
that too many architects and builders seem to have forgotten how to design using a
traditional language and simply resort to making them “look” traditional instead of following the tradition with knowledge. My hope is that the general guidelines given here
contribute to elevate the conversation about traditional architecture and help
to illustrate that while traditional moldings follow a conventional and
codified system of rules, these should be carefully calibrated to the
circumstances, character, use, and hierarchy of rooms in a particular house and
for a particular building type. In this way the use of the classical language
of architectural moldings can be expressive for our present times.
