Entasis meaning

Entasis definitions

What is Entasis?

Entasis is a term used in architecture to describe the slight convex curvature given to a column in order to correct the optical illusion of concavity that occurs when viewing a straight column from a distance. This technique was used extensively by the ancient Greeks and Romans in their architectural designs to create a sense of balance and harmony in their structures.

The History of Entasis

The use of entasis can be traced back to the ancient Greek architect Vitruvius, who wrote about the importance of this optical correction in his treatise on architecture. The Greeks believed that the human eye naturally perceives straight lines as curved when viewed from a distance, and by incorporating entasis into their columns, they were able to create a sense of perfection and beauty in their buildings.

Why Entasis is Important

Entasis is important in architecture because it allows for columns to appear straight and balanced when viewed from a distance, even though they are slightly curved. Without this optical correction, columns can appear weak or unstable, detracting from the overall beauty of a building. By carefully designing and crafting columns with entasis, architects are able to create structures that are aesthetically pleasing and visually harmonious.

The Process of Creating Entasis

Creating entasis is a meticulous process that requires careful attention to detail. Architects must first determine the ideal ratio of the column's diameter to its height in order to achieve the desired optical correction. From there, they must carefully shape the column, ensuring that the curvature is subtle yet effective in correcting the optical illusion of concavity when viewed from a distance.

Examples of Entasis in Architecture

Some of the most famous examples of entasis can be seen in the Parthenon in Athens, Greece, and the Pantheon in Rome, Italy. Both of these ancient structures feature columns with subtle curvature that create a sense of balance and harmony in their architectural design. Even today, architects continue to incorporate entasis into their designs as a tribute to this ancient technique.
