Plinth and Architecture

"These ivy-clad arcades — / These mouldering plinths ... are they all — / All of the famed, and the colossal left…?" In these lines from "The Coliseum," Edgar Allan Poe alludes to a practical feature of classical architecture. The plinth serves the important purpose of raising the base of the column it supports above the ground, thus protecting it from dampness and mold. The humble plinth is usually a mere thick block. It's humbly named, too, for the Greek word plinthos means simply "tile" or "brick." English writers have used plinth, a shortened version of the Latin form plinthus, since the mid-16th century. The word's meaning was later extended to bases for statues, vases, or busts.
