Pantheon in Rome History

Journey through time and discover the captivating history of the Pantheon of ancient Rome

The Pantheon history date back to ancient Rome. Construction of Pantheon was commissioned by Marcus Agrippa, a renowned Roman general and statesman, during the reign of Emperor Augustus in 27 BC. The original structure was a temple dedicated to the gods of Rome.

In 80 AD, the Pantheon was destroyed in a fire and subsequently rebuilt by Emperor Domitian. Tragically, that version too got destroyed in another fire in 110 AD. In early 2nd century AD, under the reign of Emperor Hadrian the Pantheon was reconstructed in its present form.

Many of ancient Roman monuments have been shattered. Luckily and surprisingly Pantheon survived the barbarian raids. With the advent of Christianity, it was consecrated as a church in 609 AD, thus preserving it from ruin or abandonment. This conversion led to the addition of Christian iconography and burial sites for prominent figures, including Italian kings and Renaissance artists.

Unlocking the Mysteries of the Pantheon’s Dome, an engineering marvel of ancient Rome

Pantheon of Rome is a proof of exemplary Roman engineering, the structure stands strong and beautiful even today. It proved to be a study material for Brunelleschi and Michelangelo, before they built their own at Florence and Vatican.

The construction of the Pantheon’s dome, hailed as one of the most remarkable achievements in architectural history, showcases the ingenuity and advanced engineering techniques of ancient Rome. At its completion, it was the largest unreinforced concrete dome in the world, a testament to the skill and expertise of its builders.

The dome’s design begins with a series of concentric rings, each composed of lighter materials as they ascend towards the oculus, the circular opening at its apex. This progressive reduction in weight minimizes stress on the structure while maintaining stability. The ingenious choice of materials played a crucial role in its success.

It was made of concrete mixed with volcanic tuff (tufo) and pumice stone. Externally the bottom part of the hemispherical dome (corresponding to the first two rings of coffering) is encased by a thick upper section of the wall which contains the outward thrust of the dome.

The exterior of the dome was adorned with white Pentelian white marble (from Athens) and stucco creating a visually appealing pattern of intersecting arches. Today, the walls of the Pantheon have lost much of their splendor. Some remains are still visible.

However, the true marvel lies in the oculus, the opening at the top of the dome.

As soon as I entered the Pantheon I felt slightly aimless. The crowd and dim light caught me unawares. The interior of the Pantheon in Rome is a breathtaking testament to ancient Roman engineering and architectural brilliance. The grandeur of the dome is simply silencing!

If you find yourself clueless too focus on the captivating features: Oculus and the Dome, Rotunda and Coffered Ceiling, Marble Flooring and Decorative Elements, Altar and Niche and the Spatial Symmetry of the place.

Unravelling the Intricate Structure of the Pantheon

Immerse yourself in the architectural splendour of Pantheon and feel a connection to the ancient world. Here’s a description of how was the dome of the Pantheon built:

Oculus and the Dome of Pantheon

The most remarkable feature is the Oculus, a circular opening at the center of the dome, which allows a beam of natural light to penetrate the interior. This oculus creates a dramatic interplay of light and shadow, casting a heavenly glow on the marble surfaces below.

Needless to say the first thing you will be attracted to will be its giant dome, with its famous hole in the top. It is called the eye of the Pantheon, or oculus. The oculus is 7.8m in diameter and is the only source of light. It is revered as the connection between the temple and Gods above.

While I was there I could witness light flowing in through the hole and falling on the inner wall of Pantheon. I stood there below that opening in the top, like millions of tourists and residents of Rome must have for centuries before me, admiring the circular piece of sky up there.

Light flows in like a huge column scanning first the floor and then the statues and moves up and up till darkness sets in. This giant dome of Pantheon Rome is the symbol of supreme achievement of Roman interior architecture!

Rotunda and Coffered Ceiling

The main interior space of the Pantheon is known as the rotunda. The walls of the rotunda are adorned with tall columns and niches, creating a sense of verticality and grandeur. The ceiling of the rotunda features a series of recessed, square panels known as coffers. These coffers not only add visual interest but also are architectural importance. They serve the purpose of reducing the weight of the dome.

Marble Flooring and Decorative Elements

The floor of the Pantheon is made of exquisite marble, showcasing intricate patterns and designs. The walls are adorned with various decorative elements, including sculptures, reliefs, and inscriptions, which provide insights into the rich history and culture of ancient Rome.

The marble floor remade in 1873, but still has the original pattern with a design of series of geometric patterns, circles and squares. The design is still the ancient Roman original. But the floor is crowded  most of the time, I hardly got a good space of the floor to photograph without people’s feet on it.

The church houses the tombs of various famous artists and Italian kings.

Altar and Niche

At the far end of the rotunda, there is an elevated area featuring an altar. This area is often used for religious ceremonies and is dedicated to the worship of Christian saints. Above the altar, a niche houses a statue of the Madonna and Child, adding a touch of religious significance to the space.

Spatial Symmetry

One of the remarkable aspects of the Pantheon’s interior is its spatial symmetry. The circular shape of the rotunda, combined with the evenly spaced columns and niches, creates a harmonious and balanced environment. This symmetry is a testament to the architectural precision and mathematical knowledge of the ancient Romans.

Pantheon Dimensions

Here is the largest unsupported dome in the world! The diameter of the dome is 43.3 m or 142 ft which is way bigger than the modern United States Capitol dome with diameter 96 ft.

Influence of the Pantheon on Roman Temple Architecture

The impact of the Pantheon on Roman temple architecture is profound, as it introduced groundbreaking design elements and left an indelible mark on subsequent structures.

The Pantheon’s innovative design, engineering brilliance, and cultural significance have solidified its position as a cornerstone of ancient Roman culture. Unlike earlier temples with front porticos, the Pantheon adopted a circular plan, symbolizing the eternal nature of the gods it was dedicated to.

Many Roman buildings, including basilicas and bathhouses, drew inspiration from the Pantheon’s design elements, such as its vaulted ceilings and grand interior spaces. The dome itself became an iconic architectural archetype.

Beyond its architectural influence, the Pantheon held immense cultural and religious significance in ancient Roman society. Originally dedicated to the pagan gods of Rome, the Pantheon served as a hub of religious activity and a place of worship. It embodied the Romans’ devotion to their deities and the reverence they held for divine powers.

The consecration of the Pantheon as a Christian church in the 7th century further solidified its cultural significance, preserving it from abandonment or destruction during a period of religious transition.

What if it rains?

My instant thought was what if it rains? The great architects of Pantheon had already catered for it! The floor is built slanted towards the edges and drains the water if it manages to hit the floor. There are holes which allow easy drainage, all this designed and made without modern tools centuries back.

Original Parts of Pantheon

Though most part of the interiors have been ripped off and very few things inside Pantheon are original and exist from the time it was made. Among them one is a section of the monument with twin grilled windows right of altar, that still retains its old charm.

The triangular pediment on the columns in the portico of Pantheon has an inscription that credits the construction of Pantheon to Marcus Agrippa (“M•AGRIPPA•L•F•COS•TERTIUM•FECIT” meaning “It was built by Marcos Agrippa in his third consulate”). This again is from the original temple built by Agrippa. It is believed that Hadrian left it as a gesture to his predecessor when he rebuilt the Pantheon.
