A primer on these touchstones of Neo-Classical architecture.
Synopsis: The author provides a good introduction to architectural trim derived from classical models. It includes a glossary of terms and illustrations showing variations in proportion and style. The text provides historical background.
Moldings are structurally non-essential building elements that help ease the transitions between large, primary structural elements. In Classical Greece and Rome, these primary elements were the plinth, the column, the capital, the entablature and the pediment. Over the years, Classical orders — the interrelationship of the dimension, proportion and location of these elements — were established. Composed of both structural and non-structural elements, they became accepted as proportionately correct and aesthetically pleasing. These strict proportions were adapted much later, when a maturing and increasingly humanistic Europe turned to the Classical past for architectural inspiration.
The Neo-Classical period lasted 150 years or so, and passed through several phases, known in the United States as Georgian (or Colonial), Federal and Greek Revival. There was no abrupt chronological dividing line between these styles, and in some cases overlap is apparent. The Classical forms were subject to various vernacular interpretations by country builders, who were quick to improvise. A craftsman who owned planes for making Federal moldings wouldn’t have been likely to discard these tools and get new ones just because the Greek Revival style happened to be in fashion.
Nonetheless, each of the periods is characterized by the use of particular moldings to embellish essential architectural components. These moldings are distinctly different in each period. In this article, the profiles of some of the moldings most characteristic of the different periods are drawn to scale (a profile is the combination of curved and straight parts that form a well-proportioned, graceful whole). They can help you date or restore period structures.
The Greeks and Romans carved their moldings in marble or stone, or…
