Egg-and-dart moldings are decorative architectural elements consisting of a repeated motif that alternates between an egg shape and a dart-like shape. This design is commonly found in classical architecture, particularly during the Neoclassical period, where it was used to emphasize elegance and symmetry in building details. The pattern reflects the influence of classical Greek and Roman styles, embodying the principles of order and harmony that are central to Neoclassical aesthetics.
