Classical Greek Architectural Orders

Sep 16, 2025

Overview

This lecture introduces the classical orders of ancient Greek architecture—Doric, Ionic, and Corinthian—and explains their distinguishing features and long-lasting influence on Western architectural design.

Introduction to Classical Orders

  • Classical orders are ancient Greek architectural styles used for over 2,500 years as the foundation of Western architecture.
  • The basic construction method used is post and lintel, where vertical posts support a horizontal lintel.
  • The three main classical orders are Doric, Ionic, and Corinthian.

Doric Order

  • Doric is the oldest and simplest order, originating in 7th-century mainland Greece.
  • Key elements: pediment (triangular top, not officially part of the order), entablature, frieze, triglyphs, and metopes.
  • Triglyphs feature three vertical marks, historically representing wooden beam ends; metopes are spaces between triglyphs, often filled with sculpture.
  • The Doric capital is plain and heavy, with a flared shape and simple slab.
  • Columns (shafts) have shallow vertical grooves (flutes) and no base, going straight into the floor.
  • Columns are built from stacked stone drums.
  • Entasis is a slight swelling in the column shaft that creates a sense of liveliness and verticality.

Ionic Order

  • The Ionic order is more elegant and slender than the Doric, considered feminine.
  • Ionic capitals have scroll-like shapes called volutes.
  • Columns have bases and a slightly different type of fluting compared to Doric.

Corinthian Order

  • The Corinthian order is the most decorative and elaborate.
  • Its distinguishing feature is a capital decorated with stylized acanthus leaves and volutes.
  • Columns have bases and are typically taller, similar to Ionic.
  • Origin myth: the capital’s design was inspired by acanthus leaves growing around a basket.

Legacy and Influence

  • Greeks invented the three classical orders; Romans and later architects adapted and continued their use.
  • Elements of classical orders remain visible in contemporary architecture.

Key Terms & Definitions

  • Post and Lintel — construction system with vertical posts supporting a horizontal lintel.
  • Order — a style or set of rules for design in classical architecture.
  • Doric — the simplest classical order, characterized by plain capitals and no column base.
  • Ionic — an order with capitals featuring spiral volutes and a column base.
  • Corinthian — the most ornate order, marked by an elaborate capital with acanthus leaves.
  • Pediment — triangular upper part of a building’s front.
  • Entablature — the horizontal structure supported by columns, consisting of the architrave, frieze, and cornice.
  • Frieze — central section of the entablature, often decorated.
  • Triglyph — a panel with three vertical grooves on a Doric frieze.
  • Metope — the space between triglyphs, sometimes sculpted.
  • Capital — the topmost element of a column.
  • Fluting — shallow grooves on the column shaft.
  • Entasis — a slight bulge in the column for visual effect.
  • Volute — a spiral scroll characteristic of Ionic and Corinthian capitals.
