Vitruvius was a Roman architect and engineer of the first century BCE whose treatise De architectura is the only major work on architecture to survive from antiquity.

How many classical orders are there?

The Greeks used three—Doric, Ionic, and Corinthian—to which the Romans added the Tuscan and Composite, giving the five orders codified in Renaissance theory.

Vitruvius and the Classical Orders

The classical orders—systems of column and entablature design codified by Vitruvius—provided a shared architectural language that governed Western building from antiquity through the nineteenth century.

Definition

The study of the classical orders of architecture and of Vitruvius's treatise, the foundational text codifying ancient architectural theory and practice.

Scope

This topic examines the only surviving architectural treatise from antiquity, Vitruvius's De architectura, and the system of orders it transmits: Doric, Ionic, and Corinthian, later joined by Tuscan and Composite. It covers Vitruvian principles of proportion, symmetry, and decorum, the anthropomorphic interpretation of the orders, and their immense afterlife in Renaissance and later theory.

Core questions

What are the classical orders, and what distinguishes each?
What principles does Vitruvius lay down for good architecture?
Why were the orders interpreted in anthropomorphic terms?
How did Vitruvius shape later architectural theory?

Key theories

Decorum and proportion: Vitruvius's doctrine that architecture should observe appropriate proportions and a decorum matching building, order, and purpose, grounding design in a system of measured relationships.
The orders as a language: John Summerson's account of the classical orders as a grammar and vocabulary—a coherent language with which architects could compose, vary, and communicate meaning.
Anthropomorphism of the column: Joseph Rykwert's study of the long tradition, rooted in Vitruvius, of understanding the column and the orders in bodily and human terms, as figures of proportion and character.

History

Vitruvius compiled De architectura in the first century BCE, drawing on Greek sources; rediscovered and printed in the Renaissance, it became the touchstone for theorists such as Alberti, Serlio, and Palladio, who systematized the five orders that dominated Western architecture until the nineteenth century.

Debates

Authority versus invention: Theorists have long debated how strictly the Vitruvian rules and the orders should bind architects, and how much room remains for invention and variation within the classical language.
