‘I doubt that’s a view shared by those we have crushed on the battlefield and made into slaves.’ Macro stared into the small flames licking up from the charred wood and ash of the fire. ‘You’re an idealist, Cato. A romantic. There is no more to it than a test of strength. We conquer because that is what Rome does, and we are good at it.’

‘There is more to it than brute strength …’ Cato began, then he paused. ‘All right, there is that. But Rome has more, much more, to offer than simply the sword. Or it might have, but for some of the emperors. I’ve seen them at close hand. Tiberius and that monster, Gaius. Each of them has wielded power with carelessness and cruelty. Claudius, for all his faults, has tried to be better. The question is, do you think young Britannicus, or Nero, will continue his good work?’

‘I hadn’t even thought about it.’ Macro yawned. ‘As long as they can pay to maintain the legions and leave the campaigning up to the professionals, then that’s all that concerns me.’

Cato stared at him. ‘I don’t believe you. You think I don’t know what stirs your heart?’

Macro turned to face him. ‘Even if I felt some of what you do about all this, then I’m old enough to know that it is a waste of time to even think about it any more. Will you change the world? Will I? No. That’s not for us. It never was, never will be. Not for men of our class. Do you not think that I once felt as you do?’ Macro paused, and continued in a kindly tone, ‘It is like a sweet delirium and age is the cure. Now, I’m tired. I’m going to sleep. You should rest too.’

Macro eased himself up, half-empty wineskin in hand, and nodded to Cato before walking across to the flap of the section tent and disappearing inside. Cato drew up his knees and wrapped his arms round them as he stared into the wavering glow of the fire. Macro’s blunt outlook on life angered and frustrated in him equal measure, as ever. Cato’s heart was young enough to harbour boundless dreams and desires to shape his future, and he demanded that others should think as he did. If they did not then it was through lack of vision or inclination. Yet, even as he felt the heat of ambition in his heart, Cato’s mind coldly considered his friend’s point of view. There was wisdom in Macro’s words, but when wisdom is proffered from the position of greater age and experience it is seldom palatable.
