Why is a pendentive used in architecture?

Usually ornamented and four to a dome, pendentives make the dome appear as if it’s hanging in the air, like a “pendent.” The word is from the Latin pendens meaning “hanging.” Pendentives are used for stabilizing a round dome on a square frame, resulting in enormous interior open space beneath the dome.

What is pendentive and Squinch?

Pendentive and squinches are architectural elements that help support a dome. They fit into the corners of a space and bridge the difference between a dome and the square room on which it sits. Both forms developed around the 5th century and were first used in Byzantine and Islamic architecture.

What are Squinches in architecture?

squinch, in architecture, any of several devices by which a square or polygonal room has its upper corners filled in to form a support for a dome: by corbelling out the courses of masonry, each course projecting slightly beyond the one below; by building one or more arches diagonally across the corner; by building in …

Who created the pendentive?

The Romans
The Romans were the first to experiment with pendentive domes in the 2nd-3rd century AD. They saw the supporting of a dome over an enclosed square or polygonal space as a particular architectural challenge.

How does a pendentive work?

In architecture, a pendentive is a constructional device permitting the placing of a circular dome over a square room or of an elliptical dome over a rectangular room. In masonry the pendentives thus receive the weight of the dome, concentrating it at the four corners where it can be received by the piers beneath.

What is a pendentive include a diagram in your explanation?

Look at the diagram above. Explain what a pendentive is. A pendentive is a curved triangular architectural element that transfers the weight from the dome to the supporting curve. It is important because the dome cannot hold all the weight and would likely collapse over time.

When was pendentive first used?

The first experimentation with pendentives began with Roman dome construction in the 2nd–3rd century AD, while full development of the form came in the 6th-century Eastern Roman Hagia Sophia at Constantinople.

What are Squinches used for?

In architecture, a squinch is a construction filling in (or rounding off) the upper angles of a square room so as to form a base to receive an octagonal or spherical dome.

When was Pendentive first used?

What was the purpose of the architectural feature called the pendentive within Byzantine churches?

In Byzantine architecture, a supporting structure of four arches with pendentives between them allowed the spaces below domes to be opened up. Pendentives allowed for weight loads to be concentrated at just four points on a more practical square plan, rather than a circle.
