Lucius nodded, as if something obscure had been made plain. ‘Your father ranted to me about this Brennos after their first encounter, and by the Gods he hated him. He said the man was the greatest threat to Rome since Hannibal.’

‘I judge by your tone you did not agree with him?’

‘I thought him obsessed.’

‘Then I too must be that.’

‘I have read all the despatches from Spain these last three years, Titus. They are alarmist to say the least and I know you had a hand in the compilation of many of them. I showed them to Aulus before he left for Illyricum and he backed up everything you said.’

‘My father did not exaggerate, and neither did I. Brennos is a serious threat to Rome.’

Lucius’s gesture was one of uncertainty; he did not want to openly disagree with the younger man on such a day and in such a setting. ‘I am apprehensive enough to ensure that I know what the fellow is up to. He is spied on constantly, as you well know.’

Titus was tempted to insist that the Senate should do more, but it was not his place to talk in such a manner to the leading man in Rome. Brennos was probably a menace greater than Lucius would grasp; the censor had not fought the man, both Titus and his father, at different times, had. A Druid from the northern islands, the man preached a message that, if implemented, would indeed make him more dangerous than Hannibal, and his name alone was a warning. Another Brennos, at the head of a great Celtic confederation, had ravaged Greece and burnt half the city of Rome hundreds of years before. His namesake was intent on uniting that same confederation, his aim not to partly burn the city but to destroy the whole empire. The carving on the sarcophagus showed him defeated, yet Brennos was far from that. Yes, he had lost a campaign, had been beaten by Aulus, but that had seemed to do no more than inspire him to continue. If anything, he was more powerful now than he had been years before.
