By What are the optical refinements?
In Greek architecture and derivatives, a set of adjustments of normal shaping and spacing made supposedly to counteract the somatic peculiarities of human vision.
What optical refinements can be seen on the Parthenon?
The shape of the column shafts, and their slight tilt from the vertical, are said to correct optical distortions so that the building appears to be perfectly regular. The columns taper towards the top, but also swell slightly part of the way up, to avoid an impression of narrowing at the centre.
What are the three visuals refinements used on the Parthenon?
The Parthenon
- 1) Inclination (the inward tilt) of the columns created the illusion of perspective in the building’s elevation.
- 2) The spacing between the columns at the corners was contracted.
- 3) The barely perceptible entasis (swelling) of the column shafts created an illusion of straight, upright columns.
How does Greek apply optical correction in their temples?
The optical corrections can be shortly summarized as follows: In a fully developed Doric temple there were practically no straight lines or right angles at all. The most important corrections were: the base or stylobate was arched upwards in the middle; the columns were tilted inwards, in the corners in two directions.
Why do Greek columns bulge in the middle?
Greek designers were very careful when they measured these columns. They knew that columns standing in a long row often looked as though they curved in the middle. To prevent this optical illusion, they made their columns bulge slightly in the middle. As a result, Greek columns look perfectly straight.
Why is the Parthenon curved?
The Roman architect Vitruvius argued that such refinements were made to counter the effects of an optical illusion: When viewed from a distance, a perfectly straight line would appear to sag, whereas the temple’s curvature would counteract that illusion.

What was the most beautiful building in Athens?
The Parthenon

What are the curves called that are used to adjust the look of Greek temples?
The oldest, simplest, and most massive of the three Greek orders is the Doric, which was applied to temples beginning in the 7th century B.C. As shown in Figure 2, columns are placed close together and are often without bases. Their shafts are sculpted with concave curves called flutes.
What was the purpose of the optical refinements?
In Greek architecture and derivatives, a set of adjustments of normal shaping and spacing made supposedly to counteract the somatic peculiarities of human vision. Also see entasis. McGraw-Hill Dictionary of Architecture and Construction. Copyright © 2003 by McGraw-Hill Companies, Inc.
How are optical refinements used in the Parthenon?
Optical refinements. Despite appearances, there are few perfectly straight lines or right angles in the Parthenon. The observer sees the eight columns of the façade as a perfectly regular array, but this is achieved by deliberately introducing subtle distortions called “optical refinements”.
