Finding the banker

''The most famous of the Seven Hills of Rome, il Campidoglio's ancient history yields layers of ruins steeped in mythology. Several important Roman temples were built atop the hill including the Temple of Juno, the Temple of Virtus and the Temple of Jupiter Optimus Maximus Capitolinus. In 79, the hill was also home to the Tabularium, the Empire's main archive. In the Middle Ages, it became the city's centre of civic government just before receiving a face lift from Michelangelo.''
