I stood under the oculus and felt the light shining down on me. Like a crew member on the Starship Enterprise or a saint chosen by God, I felt I could be beamed up at any moment and transported to another time and place even into heaven.
My first experience standing in the Pantheon, Rome’s ” temple of the gods” looking up at the vault of a “perfect heaven” was one of the most awe-inspiring moments I’ve had traveling in Italy. Commissioned in various forms by a series of Roman Emperors, the Pantheon as we know it is associated with the power and divine authority of the Emperor Hadrian who claimed it to be a perfect sphere resting in a perfect cylinder like a “shield of gold where rain would form its clear pool on the pavement below and prayers would rise like smoke toward that void where we place the gods”.
The impression created by the concentrated light of the oculus or opening at the top of the dome that illuminates the inner rotunda created such an effect that when Michelangelo first saw the Pantheon acclaimed it as “angelic and not of human design”. No CGI program or special effects department could duplicate the intensity and brilliance of this moving disc of light against the stark concrete dome.
Historians have found that the beaming light of the Pantheon is very particular at certain times of the year. Every Summer Solstice at Midsummer on June 21 the sun reaches closest to the center of the Pantheon. The oculus or Great Eye in the ceiling of the Pantheon concentrates the light of the sun’s solstice rays so that they shine from the oculus through the front door . The drama and spectacle of this blinded by the light phenomenon entering through the massive domed roof is a wonder.
Of all the great buildings constructed during the peak of the Roman Empire, only this one still stands. Described as Hadrian’s giant sun-dial, a monument from classical antiquity, a tomb (the painter Raphael, the first two kings and first queen of Italy are buried here), and a church dedicated to the Christian martyrs, the Pantheon is all of these. One of the most recognizable works of architecture on the planet, a statement that Rome remains eternal and a model for monumental construction projects (the Pantheon inspired Brunelleschi’s dome for the Cathedral in Florence, Bramante’s design for St. Peter’s Basilica and the US Capitol building) from Michelangelo to Thomas Jefferson it remains an inspiration to always strive towards the Light.
