What is a Doric frieze characterized by?

A Doric frieze is characterized by alternating triglyphs and metopes, which is a distinctive feature of the Doric order of classical architecture. The triglyphs are three vertical grooves that provide visual rhythm and a sense of structural articulation. They are usually positioned over the columns and serve as a division marker in the frieze. In between the triglyphs, the metopes often provide a space for decoration or reliefs, which can feature various motifs or narratives.

This combination of triglyphs and metopes is a hallmark of the Doric frieze, and it creates a balance of solid and void that enhances the overall aesthetic of the architectural design. The frieze's simplicity and strength reflect the ideals of the Doric order, which is known for its robust and unadorned qualities compared to the other orders, like the Ionic or Corinthian. Therefore, the distinctive alternating pattern found in the frieze effectively embodies the characteristics of Doric architecture.
