The temple, rebuilt by Domitian, stood uninjured till the middle of the fifth century. In June, 455, the Vandals, under Genseric, plundered the sanctuary, its statues were carried off to adorn the African residence of the king, and half the roof was stripped of its gilt bronze tiles. From that time the place was used as a stone-quarry and lime-kiln to such an extent that only the solitary fragment of a column remains on the spot to tell the long tale of destruction. Another piece of Pentelic marble was found January 24, 1889, near the Tullianum (S. Pietro in Carcere). It belongs to the top of a column, and has the same number of flutings,--twenty-four. This fragment seems to have been sawn on the spot to the desired length, seven feet, and then dragged down the hill towards some stone-cutter's shop. Why it was thus abandoned, half way, in a hollow or pit dug expressly for it, there is nothing to show. The Temple of Jupiter is represented in ancient monuments of the class called pictorial reliefs. I have selected for my illustration one of the panels from the triumphal arch of Marcus Aurelius, near S. Martina, because it contains a good sketch of the reliefs of the pediment, with Jupiter seated between Juno and Minerva. The temple itself is most carelessly drawn, the number of columns being reduced by one half, that is, from eight to four.[50] [Illustration: PANEL FROM THE ARCH OF MARCUS AURELIUS] There is one interesting feature of the Capitolium, which is not well known among those who do not make a profession of archæology. It was used as a place for advertising State acts, deeds, and documents, in order that the public might take notice of them and be informed of what was going on in the administrative, military, and political departments. This fact is known from a clause appended to imperial letters-patent by which veterans were honorably discharged from the army or navy, and privileges bestowed on them in recognition of their services. These deeds, known as _diplomata honestæ missionis_, were engraved on bronze tablets shaped like the cover of a book, the original of which was hung somewhere in the Capitolium, and a copy taken by the veteran to his home. The originals are all gone, having fallen the prey of the plunderers of bronze in Rome, but copies are found in great numbers in every province of the Roman empire from which men were drafted.[51] These copies end with the clause:-- "Transcribed (and compared or verified) from the original bronze tablet which is hung in Rome, in the Capitolium"--and here follows the designation of a special place of the Capitolium, such as,-- "On the right side of the shrine of the _Fides populi romani_" (December 11, A. D. 52). "On the left side of the _ædes Thensarum_" (July 2, A. D. 60). "On the pedestal of the statue of Quintus Marcius Rex, behind the temple of Jupiter" (June 15, 64). "On the pedestal of the _ara gentis Iuliæ_, on the right side, opposite the statue of Bacchus" (March 7, 71).
