'Up early, or couldn't you sleep?' Macro called out as he strode over to join Cato.

'Not much chance of anyone sleeping when you start snoring.' Cato tossed the stopper aside into the grass. 'At least we weren't troubled by anything else last night. That's something to be thankful for.'

Further along the shore the other passengers and the crews from the boats were rising and rolling up their bedrolls ready to continue the voyage upriver. Hamedes approached them, carrying his kitbag over his shoulder.

'Morning, sirs. I heard there was some excitement last night.'

'You could say that,' Macro replied.

Hamedes tossed his bag down and squatted in front of them. 'The optio told me about the snake just now. Seems you had a close escape. The venom of the Nile cobra can kill a man within the hour. You're very lucky, sir.'

'Funny, I thought I was unlucky that it happened at all.'

The priest tilted his head to one side. 'Perhaps it was an omen. A message from the gods. A warning perhaps.'

'Then again, perhaps it was just a bloody snake which took a wrong turning.' Macro stood up and pointed to two of the legionaries standing by the nearest fire. 'You, and you. Get the tent down and stowed. Make sure the bedrolls are put on the same boat.'

Cato turned to Hamedes and was silent a moment before he spoke. 'A message? I think you might be right.'

'Oh?' A brief look of surprise flashed across the priest's face.

'Yes,' Cato continued. 'We seem to have been dogged by bad luck ever since we began our hunt for Ajax here in Egypt. I'm beginning to wonder if we've offended some of the local gods. You're the man with the expertise here, Hamedes. How do we go about appeasing your gods? Who should we offer prayers to? What sacrifice should we make?'

Macro glanced at his friend. 'Since when did you come over all religious?'

'There's been plenty of times in the last few months when fortune has played us false, Macro. It could be mere coincidence, but I doubt it. On one or two occasions, perhaps, but as often as we have endured it, then a man is right to suspect that the gods, or someone else, are playing their hand.'

Macro puffed his cheeks, not quite sure how to respond. 'You really think an offering is necessary, sir?'

'It would give me some peace of mind,' Cato admitted. 'Will you see to it, Hamedes, on our behalf?'

'Of course, sir.'

'As soon as you can.'

'I will do what I can. The rites associated with good fortune and warding off bad luck were beyond my remit, sir. I was entrusted with more basic offerings. But I will find out for you when we reach Diospolis Magna and I can consult the priests there.'

Cato stared at him and then nodded. 'Very well, that will have to do.' He took a deep breath and stood up. 'Meanwhile, let's get the convoy under way again. The sooner we reach our destination, the better.'

The convoy continued up the river, passing beyond the delta on to the single expanse of water that flowed through the heart of the great desert that stretched west from the Erythraeum Sea across the continent and formed the southernmost boundary of the Empire. From the river Cato could see the rocky scarps that rose up beyond the narrow belt of cultivated land spilling out beyond both banks of the Nile. Between stretches of reeds and palm trees he saw great numbers of fields tended by peasants and tilled by oxen drawing heavy ploughs as they turned over the dark silted soil that was the source of the province's great wealth. Before the time when Rome had coveted the fertile farmlands of Egypt, such wealth had funded the ambitions of the Ptolemies, and before them the ancient lineage of the old Pharaohs dating back to time beyond record.

Though they were forgotten, they had lived in an age of marvels, Cato mused as the convoy passed by the trio of pyramids, guarded by a giant Sphinx, a short distance downriver from Memphis. Though he had seen them several days earlier, on the way to report to Petronius, Cato still viewed them with awe as he stood on the foredeck shading his eyes as he stared. They were built on the scale of mountains, it seemed, though geometrically perfect in a manner that nature could never achieve. The sides seemed to be glassy smooth for the most part, and patches of what looked like gold leaf reflected the sun's rays in such dazzling splendour that Cato thought they would have been impossible to behold when in their prime.

'Quite a sight,' said Macro as he came forward to stand beside Cato. He stared a moment longer and then shook his head. 'Hard to believe it's the handiwork of the gypos, ain't it?'

'That's hardly a fair comment.' Cato gestured to a village on the shore. 'These people are living in the shadows of their ancestors. They are not the same.' He paused for a moment in reflection. 'Perhaps one day they will say the same of our ancestors when Rome is little more than a curiosity. When our great monuments are crumbling back into the ground.'

'Pfft! You talk utter bollocks sometimes, Cato.' Macro nudged him. 'You know you do.' He cleared his throat and then imitated the same hushed and reverential tones of his friend as he continued. 'Rome is the darling of the gods, brought forth into the world to be a shining beacon of all that is great and best. In the distant future people will stand in front of the gates of Rome and look in wonder on our mighty works and despair…'

'Have you quite finished?' Cato asked tersely.

Macro sniffed. 'Give me a moment, I'm sure I might have missed something pretentious I could have said.'

'Fuck off.'

'Now that's spoken like a soldier. Brief, and to the point. Come, forget about all them dusty piles of stone and get into the shade before you start getting even more light-headed, eh?'

Macro slipped back under the awning and sat down. Cato stared at the pyramids for a little longer, but Macro's words had robbed them of some of their mystique and with a sigh he turned and joined Macro and Hamedes in the shade.

Ten days after the convoy left Alexandria the barges sailed round the final bend in the river before Diospolis Magna just after the sun had fallen behind the arid mountains on the western bank. On the opposite bank towered the pylons of the largest temple complex Cato had ever seen. Tall wooden masts rose from brackets on the carved walls and tattered banners of faded red wafted and flickered in the evening breeze. A tall mud-brick wall surrounded the temple, giving it the appearance of a vast fortress. A stone landing stage stood a short distance from the edge of the river, where a more recent quay constructed from wood lined the bank of the Nile.

'Karnak,' Hamedes said with reverence, and then pointed further along the bank to another, far smaller complex. 'And that's the temple of Amun. The city lies beyond.'

The captain of the barge sat at the tiller and gently heaved it away from him as he steered in towards the quay. A number of soldiers were standing guard along the quay and on towers erected behind the walls. As the flotilla approached, a party of soldiers emerged from the ornate landing platform and descended the ramp on to the quay to assist with mooring the barges. The crews tossed ropes across the water to them and one by one the barges were hauled in and the ropes fastened to worn wooden cleats lining the quay.

The two Roman officers and the priest gathered their kitbags and stepped ashore. Cato stopped the optio in charge of the mooring party.

'Where is the army headquarters?'

'Who wants to know?'

Macro stepped forward to tear a strip off the optio for his insubordination but Cato raised a hand to stop him. They were wearing only their standard-issue tunics. Their armour, and insignia, were packed in their kitbags.
