Step by Step
D
Doric — the simplest order
No base, with a plain, unadorned echinus capital. Seen at the Parthenon and Paestum. Triglyphs and metopes form the alternating frieze elements characteristic of Doric design.
I
Ionic — elegant and scrolled
Features a base and distinctive volute (scroll) capitals. Seen at the Erechtheion in Athens.
C
Corinthian — the most ornate
The most elaborate order, topped with an acanthus leaf capital. Seen at the Lysicrates monument.
R
Roman additions and refinements
Rome added two more orders: Tuscan (a simplified Doric with a base) and Composite (combining Ionic and Corinthian elements). Entasis — a subtle swelling in a column's shaft — corrects the optical illusion that would otherwise make straight columns appear concave. According to Vitruvius, the orders carried symbolic associations: Doric represented masculine strength, Ionic feminine elegance, and Corinthian youthful beauty. These orders have been used continuously from ancient Greece to the present day.
Applied Walkthrough
1
Standing before the Parthenon, you'd see the Doric order in its simplest form — no base, and a plain, unadorned capital, with alternating triglyphs and metopes forming the frieze above.
2
At the Erechtheion nearby, the Ionic order instead greets you with distinctive scrolled (volute) capitals atop columns that do have bases — a more elegant, refined visual effect than Doric's severity.
3
The Lysicrates monument showcases the most ornate of the three original Greek orders, Corinthian, with its capital elaborately carved into overlapping acanthus leaves.
4
Looking closely at any of these columns, you'd notice a subtle swelling partway up the shaft called entasis — a deliberate optical correction preventing the column from appearing concave, or pinched, to the human eye; and centuries later, Rome would add two further orders, Tuscan and Composite, to this same classical vocabulary — a system so enduring it's still referenced in classical-revival buildings today.
Exam Application
Exams test whether you can identify each of the five orders (Doric, Ionic, Corinthian, Tuscan, Composite) by its distinctive capital, and whether you understand entasis and its optical purpose.
⚠ Common Trap
The most common trap is confusing which order has which capital style — remember Doric is plain, Ionic has scrolls (volutes), and Corinthian has acanthus leaves — a progression from simplest to most ornate.
