VIRGILIUS THE SORCERER 373
as well as foes without. Virgilius spent many days in deep thought, and at length invented a plan which was known to all as the ' Preservation of Rome.'
On the roof of the Capitol, which was the most famous public building in the city, he set up statues representing the gods worshipped by every nation subject to Rome, and in the middle stood the god of Rome herself. Each of the conquered gods held in its hand a bell, and if there was even a thought of treason in any of the countries its god turned its back upon the god of Rome and rang its bell furiously, and the senators came hurrying to see who was rebelling against the majesty of the empire. Then they made ready their armies, and marched against the foe.
Now there was a country which had long felt bitter jealousy of Rome, and was anxious for some way of bringing about its destruction. So the people chose three men who could be trusted, and, loading them with money, sent them to Rome, bidding them to pretend that they were diviners of dreams. No sooner had the messengers reached the city than they stole out at night and buried a pot of gold far down in the earth, and let down another into the bed of the Tiber, just where a bridge spans the river.
Next day they went to the senate house, where the laws were made, and, bowing low, they said, ' Oh, noble lords, last night we dreamed that beneath the foot of a hill there lies buried a pot of gold. Have we your leave to dig for it?' And leave having been given, the messengers took workmen and dug up the gold and made merry with it.
A few days later the diviners again appeared before the senate, and said, ' Oh, noble lords, grant us leave to seek out another treasure, which has been revealed to us in a dream as lying under the bridge over the river.'
And the senators gave leave, and the messengers hired boats and men, and let down ropes with hooks, and at length drew up the pot of gold, some of which they gave as presents to the senators.
