The
Pantheon is a building in Rome which was originally built as a
temple to the seven deities of the seven planets in the Roman
state religion, but which has been a Christian church since the
7th century. It is the best-preserved of all Roman buildings and
the oldest important building in the world with its original
roof intact. It has been in continuous use throughout its
history. Although the identity of the Pantheon's primary
architect remains uncertain, it is largely assigned to
Apollodorus of Damascus.
The interior of the Pantheon in the 18th century, painted by
Giovanni Paolo PaniniThe original Pantheon was built in 27 BC-25
BC under the Roman Empire, during the third consulship of Marcus
Vipsanius Agrippa, and his name is inscribed on the portico of
the building. The inscription reads
M·AGRIPPA·L·F·COS·TERTIUM·FECIT, "Marcus Agrippa, son of Lucius,
consul for the third time, built this." It was originally built
with adjoining baths and water gardens.
In fact, Agrippa's Pantheon was destroyed by fire in AD 80, and
the current building dates from about 125, during the reign of
the Emperor Hadrian, as date-stamps on the bricks reveal. It was
totally reconstructed, with the text of the original inscription
added to the new facade, a common practice in Hadrian's
rebuilding projects all over Rome. The building was later
repaired by Septimius Severus and Caracalla. Hadrian was a
cosmopolitan emperor who traveled widely in the east and was a
great admirer of Greek culture. He seems to have intended the
Pantheon, a temple to all the gods, to be a kind of ecumenical
or syncretist gesture to the subjects of the Roman Empire who
did not worship the old gods of Rome, or who (as was
increasingly the case) worshipped them under other names.
In 609 the Byzantine emperor Phocas gave the building to Pope
Boniface IV, who reconsecrated it as a Christian church, the
Church of Mary and all the Martyr Saints (Santa Maria ad
Martyres), which title it retains.
The coffers for the concrete dome were poured in molds, probably
on the temporary scaffolding; the oculus admits the only light
(and rain).The building's consecration as a church saved it from
the abandonment and spoliation which befell the majority of
ancient Rome's buildings during the early mediaeval period. Paul
the Deacon records the spoliation of the building by the Emperor
Constans II, who visited Rome in July 663:
remaining at Rome twelve days he pulled down everything that in
ancient times had been made of metal for the ornament of the
city, to such an extent that he even stripped off the roof of
the church [of the blessed Mary] which at one time was called
the Pantheon, and had been founded in honor of all the gods and
was now by the consent of the former rulers the place of all the
martyrs; and he took away from there the bronze tiles and sent
them with all the other ornaments to Constantinople.
The only other loss has been the external sculptures, which
adorned the pediment above Agrippa's inscription. The marble
interior and the great bronze doors have survived, although the
latter have been restored several times.
During the reign of Pope Urban VIII, the Pope ordered the bronze
ceiling of the Pantheon's portico melted down. Most of the
bronze was used to make bombards for the fortification of Castel
Sant'Angelo, with the remaining amount used by the Apostolic
Chamber for various other works. (It is also said that the
bronze was used by Bernini in creating the baldachin above the
main altar of St. Peter's Basilica, but according to at least
one expert, the Pope's accounts state that about 90% of the
bronze was used for the cannon, and that the bronze for the
baldachin came from Venice.[1]) This led to the Latin proverb, "Quod
non fecerunt barbari, fecerunt Barberini" ("What the barbarians
did not do, the Barberinis [family name of Urban VIII] did").
Since the Renaissance the Pantheon has been used as a tomb.
Among those buried there are the painters Raphael and Annibale
Caracci, the architect Baldassare Peruzzi and two kings of
Italy: Vittorio Emanuele II and Umberto I, as well as Umberto's
Queen, Margherita. In the 15th century, the Pantheon was adorned
with paintings: the best known is the "Annunciazione" by Melozzo
da Forlì.
Although Italy has been a republic since 1946, volunteer members
of Italian monarchist organisations maintain a vigil over the
royal tombs in the Pantheon. This has aroused protests from time
to time from republicans, but the Catholic authorities allow the
practice to continue, although the Italian Ministry of Cultural
Heritage [2] is in charge of the security and maintenance. The
Pantheon is still a church and Masses are still celebrated in
the church, particularly for weddings.
The building is circular with a portico of three ranks of huge
granite Corinthian columns (eight in the first rank and two
groups of four behind) under a pediment opening into the rotunda,
under a coffered, concrete dome, with a central opening (oculus),
the Great Eye, open to the sky. The weight of the dome is
concentrated on a ring of voussoirs 8.5 metres in diameter (almost
30 feet) which form the oculus. A rectangular structure links
the portico with the rotunda. In the walls at the back of the
portico were niches for statues of Caesar, Augustus and Agrippa.
The large bronze doors to the cella, once plated with gold,
still remain, but the gold has long since vanished. The pediment
was decorated with a sculpture in bronze showing the Battle of
the Titans - holes may still be seen where the clamps which held
the sculpture in place were fixed.
The height to the oculus and the diameter of the interior circle
are the same (43 metres, or 142 feet 6 inches), so the whole
interior would fit exactly within a cube (alternatively, the
interior could house a sphere 43 metres in diameter). The dome
is the largest surviving from antiquity and was the largest dome
in western Europe until Brunelleschi's dome of the Duomo of
Florence was completed in 1436. It was covered with gilded
bronze plates.
Antoine Desgodetz' elevation of the Pantheon in Les edifices
antiques de Rome, Paris, 1779: engravings served designers who
never travelled to Rome.The interior of the roof is intended to
symbolize the heavens. The Great Eye, 27 feet across, at the
dome's apex is the source of all light and is symbolic of the
sun. Its original circular bronze cornice remains in position.
The interior features sunk panels (coffers), which originally
contained bronze star ornaments. This coffering was not only
decorative, but also reduced the weight of the roof, as did the
elimination of the apex by means of the Great Eye. The top of
the rotunda wall features a series of brick-relieving arches,
visible on the outside and built into the mass of the brickwork.
The Pantheon is full of such devices - for example, there are
relieving arches over the recesses inside - but all these arches
were, of course, originally hidden by marble facing.
It may well be noted that the proportions of the building are in
discord with respect to the classical ideal. Most evident is the
rather large pediment, which appears far too "heavy" for the
columns supporting it. The reason for this was the expectation
that the building would be much taller than it actually is,
which would affect larger columns. However, by the time the
pediment was built, it was realised that the supply of imported
stone for the columns were not enough to build to its
anticipated height and thus the builders had to settle with a
building that is somewhat out of proportion.
The lower parts of the interior of the Pantheon are richly
decorated in coloured marbles; the coffered upper parts are
unadorned concrete.The composition of the Roman concrete used in
the dome remains a mystery. An unreinforced dome in these
proportions made of modern concrete would hardly stand the load
of its own weight, since concrete has very low tensile strength,
yet the Pantheon has stood for centuries. It is known from Roman
sources that their concrete is made up of a pasty hydrate lime;
pozzolanic ash and lightweight pumice from a nearby volcano; and
fist-sized pieces of rock. In this, it is very similar to modern
concrete. The high tensile strength appears to come from the way
the concrete was applied in very small amounts and then was
tamped down to remove excess water at all stages. This appears
to have prevented the air bubbles that normally form in concrete
as the material dries, thus increasing its strength enormously.
As the best preserved example of monumental Roman architecture,
the Pantheon was enormously influential on European and American
architects from the Renaissance to the 19th century. Numerous
city halls, universities and public libraries echo its
portico-and-dome structure. Examples of notable buildings
influenced by the Pantheon include Thomas Jefferson's Rotunda at
the University of Virginia, Low Library at Columbia University,
New York, and the State Library of Victoria in Melbourne,
Australia. Some changes have been made in the interior
decoration, however. Much fine marble has been removed in the
course of the centuries, and there are capitals from some of the
pilasters in the British Museum.
