The direction of the Forum is nearly from north to south, trending a little from north-east to south-west. It is surprisingly small to have contained such a large number of buildings, and to have bulked so prominently in the eye of the world; its greatest length being only six hundred and seventy-one feet, and its greatest breadth about two hundred and two feet. Beginning at the north end, we see before us the vast mass of the ancient Capitol, the proudest symbol of the majesty of Rome, crowned with the great staring medieval structures of the Roman municipality, rising up into the campanile of Michael Angelo. Until of late years, this renowned building was completely buried beneath a huge mound of rubbish. Now that it has been removed, the venerable fabric stands out distinctly to view, and we behold the massive walls of the Treasury, the Record Office, and the Senate House. The lowest part, constructed of huge blocks of volcanic stones, was the AErarium or Public Treasury, and is supposed to have been formed out of the original wall of the city of the Sabines, which surrounded the hill of Saturn, as the Capitoline Mount was originally called, long before Romulus laid the foundation of Rome. As the Roman army was paid in coppers, spacious cellars were required for storing the coin, and these were provided in the underground vaults of the Treasury, partially cut out of the volcanic rock of the Capitol, on which the building rests. Above the Treasury, on the second floor, we see the remains of the Doric portico of the Tabularium or Public Record Office, where the records of Rome, engraved upon bronze tablets, were kept. The place is now converted into an architectural museum, where all the most interesting sculptured fragments found in the Forum are preserved, and are exhibited by gaslight owing to the darkness. These buildings, it must be remembered, form the back of the Capitol fronting the Forum. Strictly speaking, they do not belong to the Forum, which should be traced only from their verge.
