He had, however, to discover that if to change over to Caesar was the safer course, to turn a political somersault once more, to try and undermine the work of the master, meant simply ruin. We have the story of his sixth and last transformation from Caesar himself, who was not, however, in Italy at the time.[199] Credit in Italy had been seriously upset by the outbreak of Civil War, and Caesar had been at much pains to steady it by an ordinance which has been alluded to in the last chapter.[200] In 48 Caelius was praetor; in the master's absence he suddenly took up the cause of the debtors, and tried to evoke appeals against the decisions of his colleague Trebonius,--a great lawyer and a just man. Failing in this, he started as a downright revolutionary, proposing first the abolition of house-rent, and finally the abolition of all debts; and Milo, in exile at Massilia, was summoned to help him to raise Italy against Caesar. This was too much, and both were quickly caught and killed as they were stirring up gladiators and other slave-bands among the latifundia of South Italy. Caelius' letters give us a chance of seeing what that life of the Forum really was which so fascinated the young men of the day, and some of the old, such as Cicero himself. We can see these children playing on the very edge of the crater, like the French noblesse before the Revolution. In both cases there was a semi-consciousness that the eruption was not far off,--but they went on playing. What was it that so greatly amused and pleased them?
