The crowd had thinned and as they went downhill several senators joined them, hailing the emperor and then the rest of the party. Hadrian was always amused to see the slaves doing the same thing with the slightest of nods and gestures. Theirs was a small world as well in many ways, as attendants of great men.

‘You are in need of a new tribune,’ Laberius commented once they had resumed.

‘Yes.’ Hadrian had suspected as much, for the stripling in the post had done six months and on brief acquaintance had struck him as the sort never to do more than the barest minimum. No doubt Laberius was better informed.

‘Anyone in mind?’

That was surprisingly direct and strange for the matter was not really up to him.

‘I would guess that the legatus will find someone suitable.’ That was the usual way, with the governor of the province putting forward a name to the emperor for approval, more often than not recommending someone who had in turn been recommended to him.

‘Wouldn’t do any harm if you wrote to him with a suggestion.’

More petitioners clustered where the road turned, and this caused a little delay. In front of them, an older senator was telling a story about Augustus and a poet who had waited outside the palace for weeks, hoping that he could get the Caesar’s attention for long enough to recite a composition in his praise. ‘Well Augustus spotted the ragged fellow, and made sure to ignore him, always turning away. He wanted money, of course, they all do. When did you ever hear of a rich poet who did not inherit his wealth?’

Hadrian half listened, for the old senator had a carrying voice and either did not realise how loudly he was speaking or did not care. It took an effort not to chip in with half a dozen examples of poets whose verse had earned them considerable wealth.

‘Perhaps I could think of someone,’ Hadrian said softly. If Laberius wanted to play little games then why not make it hard for him.

‘Day after day it went on,’ the senator continued, half shouting. ‘Sun and rain, there the poor fellow was and each time the divine Augustus strode past. Took to coming earlier and earlier and finally to camping out to be closest to the edge of the road.’

‘Perhaps you could,’ Laberius said. ‘And perhaps even better you would consider Licinianus – I mean young Crassus Frugi, or Piso as he likes to be known.’

Hadrian had a good memory for names, even long names like Caius Calpurnius Piso Crassus Frugi Licinianus. It was a point of pride never to forget, especially if he had met someone, but even so it was a moment before he could picture the face. It was not a pretty face, speckled with moles, some of them large, the expression dull and sullen. ‘An admirable young man, I believe,’ he said, lying fluently. ‘I did not know that he was eager for service. He must already be twenty-two.’
