Architectural Highlights of Pantheon Rome Oculus
Circular Opening
The Oculus is a perfectly circular opening at the top of the dome, its circular shape allows for an even distribution of stress and weight across the dome, ensuring stability and durability.
Harmonious Proportions
The diameter of approximately 8.8 meters (29 feet) was precisely chosen to create a visually harmonious space within the temple.
Ingenious Engineering
The use of concrete, the stepped "cassettes" around the opening, and the gradually thinning dome towards the top are all examples of the ingenious engineering that went into creating the Oculus.
Practical Design
The Pantheon's oculus serves a dual purpose. It prevents rainwater accumulation while also transforming into a sundial, marking time with sunlight across the Pantheon's interior.
Structure of Pantheon Rome Oculus
The Oculus is positioned exactly in the center of the dome with 44.4 meters wide opening, acting both as a source of light and a practical purpose to contact heaven.
To ensure stability and support for such a massive structure, the edges are composed of heavy stone blocks making them approximately seven meters thick. Amazingly, near the oculus, the dome is remarkably thin with only 1.2 meters of thickness supporting this impressive feat - due to clever tricks used by Hadrian such as mainly using pumice for construction near the oculus instead of heavier stones from lower down in his own quarries far away from Rome so that there was no extra weight created by transporting bulkier materials over long distances.
Deatiled Account of The Roman Pantheon ArchitectureWho Designed Pantheon Rome Oculus?
Around 120 A.D., Emperor Hadrian initiated the construction of the Pantheon, drawing inspiration from Greek temples and classical architecture. The ingenious mind behind the Pantheon's oculus is believed to be the brilliant Roman architect Apollodorus of Damascus.
Notably distinct for its era, the Pantheon surpassed any previous structures in Rome with its exceptional intricacy. Hadrian envisioned a grand design comprising three main elements: a stately portico, a circular domed rotunda or vault with a cupola, and a seamless connection harmonizing these components.
