L. Capitolium (Temple of Jupiter Optimus Maximus) (XLI in plan). —
This national sanctuary of ancient Rome, designed by the elder Tarquin
and built by his son Superbus, was dedicated by M. Horatius Pulvillus,
consul, on September 13, 509 B. c. Writers describe it as raised on a
platform 61.62 metres lonj;. and 57.17 wide, in the middle of a sacred
area, which was bounded on three sides by precipitous cliffs. There were
three rows of columns on the front of the temple, but none at the back;
the style of architecture was pure Etruscan, low and heavy, with intercolumniation
so wide (areostyle) as to require the use of wooden architraves. The-cella
was divided into three compart, ments, the middle one sacred to Jupiter,
the one on the left to Juno Regina, the one on the right to Minerva. The
pediment was crowned by a quadriga of terra-cotta, in the manner of an
acroterium; and the statue of the Father of the (iods was of the same
material. It was the work of Turianus of Fregenae, who had painted the
face of the god in vermilion, and dressed his body with the tunica palmata
and the toga picta. Considering that the wooden architraves must have
been covered likewise with panels of painted terra cotta, the roof lined
with antefixae, etc., we may assume that the old Capitolium did not differ
from the contemporary temples of southern Etruria, a splendid specimen
of which, discovered at Faleria, is now exhibited in the Villa Giulia
outside the Porta del Popolo.
In 386 B. c. the rugged and uneven surface of the hill around the temple
was made level by means of gigantic substructures. which rose from the
level of the plain to that of the temple itself, a work called " insane
" by Pliny, and classed by Livy among the wonders of Kome. The C'apitolium
was only accessible from the side of the clivus by means of stately stairs,
a kind of "scala santa," which Caesar and Claudius ascended on their knees.
On July 6, 83 B. c., a malefactor, whose name was never discovered, set
the building ablaze. Sulla undertook its reconstruction, for which purpose
he laid his hands on some of the columns of the Temple of Jupiter the
Olympian at Athens. Sulla's work was continued by Lutatius Catulus (the
builder of the Tabularium), and finished by Julius Caesar in 46. A second
restoration took place in the year 9 B. c. under Augustus, a third in
74 A. D. under Vespasian, and the last in the year 82 under Domitiau.
Domitian's temple was of the same length and width as its predecessors,
but higher and more svelte. It had Corinthian columns of pentelic
marble.
For many generations topographers have discussed which of the two summits
of the Capitoline hill was occupied by the temple, which by the citadel.
A discovery made on November 7, 1875, gave me the first clue to the solution
of the difficulty. While building the foundations of the new rotunda in
the garden of the Palazzo dei Conservatori (where the works of art dug
up on the Esquiline are now exhibited), we discovered the edge of the
platform built by the Tarquins, and upon it a fragment of one of the columns
of pentelic marble pertaining to the last restoration of Domitian. Such
a find, taken by itself, would not have been conclusive ; but compared
with others made in the course of the last four centuries, it proves beyond
doubt that the Capitolium stood on the summit of Monte Caprino, and consequently
that the Arx and the Tarpeiau rock must be placed on the Aracocli side.
First as to the insnua: nulmtructiontus which supported the
sacred area. They have been seen and described by Flaminio Vacca on the
side of the Piazza della Consolazione, by Sante Bartoli on the side of
the Piazza Montanara, by Ficoroni on the side of the Via iIi Torre de'
Specchi, their thickness exceeding five metres. The travertine facing
of these walls was covered with inscriptions and dedications in honor
of the great Roman god by the kings and the nntions of the world. One
cannot read these historical documents, these messages of friendship and
gratitude from the remotest corner of the earth, without acquiring a new
sense of the magnitude and power of Rome.1 These dedications are found
only on the side of the Monte Caprino.
