When Sulla was unable to induce Scipio to change, he sent him away with his son unharmed. He also sent other envoys to Norbanus at Capua to open negotiations, either because he was apprehensive of the result (since the greater part of Italy still adhered to the consuls), or in order to play the same game on him that he had played on Scipio. As nobody came back and no answer was returned (for it seems that Norbanus feared lest he should be accused by his army in the same way that Scipio had been), Sulla again advanced, devastating all hostile territory. Norbanus did the same thing on other roads. Carbo hastened to the city and caused Metellus, and all the other senators who had joined Sulla, to be decreed public enemies. It was at this time that the Capitol was burned. Some attributed this deed to Carbo, others to the consuls, others to somebody sent by Sulla. It was a great mystery; nor am I able now to conjecture what caused the fire. Sertorius, who had been some time previously chosen prætor for Spain, after the taking of Suessa fled to his provincet and as the former prætors refused to recognize his authority, he stirred up a great deal of trouble for the Romans there. In the meantime the forces of the consuls were constantly increasing from the major part of. Italy, which still adhered to them, and also from the neighboring Gauls on the Po. Nor was Sulla idle. He sent messengers to all parts of Italy that he could reach, to collect troops by friendship, by fear, by money, and by promises. In this way the remainder of the summer was consumed on both sides.
