In Classical architecture and derivatives, the column and entablature developed by the Dorian Greeks. Characterized by sturdy proportions, a simple capital, a frieze usually having regularly spaced triglyphs and metopes, and mutules in the cornice; plainer than the Corinthian order or the Ionic order (although the Tuscan order later introduced by the Romans was even plainer). The Roman Doric column has a base but is usually not fluted (see illustration of base, which follows); in contrast, the Greek Doric column is usually fluted but has no base. Compare with Tuscan order.
