Cato saw a flush of embarrassment in the young prince’s face, before Tincommius replied, in Latin, ‘I was younger then, sire, and more easily led. Since I’ve learned more of Roman ways, and fought alongside them, I’ve come to respect them and value what they have to offer the Atrebatans.’

‘And what do they have to offer the Atrebatans?’ the Greek merchant interrupted. ‘I’d be interested in your opinion. To hear it straight from the horse’s mouth, as it were.’

‘I should have thought a Greek would know.’

The merchant smiled at Tincommius. ‘Forgive me, but we’ve lived under Roman rule too long to remember what it was like before. And since I’m investing quite a fortune in developing trading links with the new province I merely wish to understand the native view of the situation. If you wouldn’t mind, young man?’

Tincommius looked round the table uncomfortably, meeting Macro’s curious gaze only briefly.

‘Tincommius, tell us,’ Verica urged him gently.

‘Sire, like you I’ve lived a while in Gaul and have seen what you saw: the great towns with all their marvels. And you’ve told me of the endless network of trade routes that bind the empire together, of the wealth that flows along them to the very fringes of their world. Above all, you told me there is order. An order that tolerates no conflict, that forces its subjects to live in peace with each other, or face terrible consequences. That’s why Rome must prevail.’

Macro watched Tincommius closely. The man seemed sincere enough. But you could never really tell with these Britons, Macro reflected as he downed another horn of ale.

‘As long as I can remember the Atrebatans have been fighting other tribes,’ Tincommius continued. ‘Always the Durotrigans, and lately the Catuvellaunians, who so cruelly threw you out, sire.’

Verica frowned at the tactless mention of his eviction from the throne by Caratacus and his tribe.

‘I never knew any different. War was our way, the way of all the Celtic tribes of this island. It’s why we live in these poor huts, why we can never have our own empire. We have no common purpose, so we must bind ourselves to one who has . . . the Emperor.’

‘Although Caratacus hasn’t been doing too badly on that score!’ Macro chipped in, with a faint slur to his voice. Cato did a quick calculation and realised with alarm that Macro was already into his fourth horn of beer - on top of all the wine he had been drinking that afternoon. Macro nodded at Tincommius. ‘I mean, look how many tribes he’s managed to line up against us so far. If we don’t kill the bastard quickly, who knows what trouble he’s going to cause our general?’
