Egg-and-dart. This week’s Building Language term explores the extensive terminology associated with classical architecture. Egg-and-dart is a form of ornament standard in classical inspired architecture, including the vastly popular Beaux Arts and Classical Revival styles in Indianapolis. Egg-and-dart consists of two elements: first, the echinus, which is a type of circular molding with an egg-like form, and second, a groove and raised border, which surrounds each echinus. The tops of the “eggs” or echinus are then trimmed at the top of each band. Egg-and-dart is typically used on classical cornices or friezes as a small band of ornament.
