The business life of Rome was in every way worthy of her position as an imperial city, and her business centre was becoming the greatest exchange of the commercial world of the day. The forum still drew its largest crowds to listen to the voice of the lawyer or the orator; but these attractions were occasional and the constant throng that any day might witness was drawn thither by the enticements supplied by the spirit of adventure, the thirst for news and the strain of business life. The comic poet has drawn for us a picture of the shifting crowd and its chief elements, good and bad, honest and dishonest. He has shown us the man who mingles pleasure with his business, lingering under the Basilica in extremely doubtful company; there too is a certain class of business men giving or accepting verbal bonds. In the lower part of the Forum stroll the lords of the exchange, rich and of high repute; under the old shops on the north sit the bankers, giving and receiving loans on interest.[158] The Forum has become in common language the symbol of all the ups and downs of business life,[159] and the moralist of later times could refer all students, who wish to master the lore of the quest and investment of money, to the excellent men who have their station by the temple of Janus.[160] The aspect of the market place had altered greatly to meet the growing needs. Great Basilicae--sheltered promenades which probably derived their names from the Royal Courts of the Hellenic East--had lately been erected. Two of the earliest, the Porcian and Sempronian, had been raised on the site of business premises which had been bought up for the purpose,[161] and were meant to serve the purposes of a market and an exchange.[162] Their sheltering roofs were soon employed to accommodate the courts of justice, but it was the business not the legal life of Rome that called these grand edifices into existence.
