with the right offerings, Jupiter might actually come and help you. It was highly unlikely that Woden would do the same. Even if you were one of his descendants – Woden-born, as Ballista himself was – probably the best you could hope from the Allfather was that he would leave you alone until your final battle. Then, if you fought like a hero, he might send forth his shield maidens to carry you to Valhallah. All of which left Ballista wondering why he had dedicated that golden bowl. With a heavy sigh, he decided to think about something else. Theology was not for him.
He turned his thoughts to his mission. It was reasonably straightforward. By the standards of the Roman imperial bureaucracy, it was very straightforward. He had been appointed the new Dux Ripae, commander of all the Roman forces on the banks of the rivers Euphrates and Tigris and all the land in between. The title was rather grander on paper than in reality. Three years ago, the Sassanid Persians, the new and aggressive empire to the east, had attacked Rome's eastern territories. Burning with religious fervour, hordes of their horsemen had swept up the riverbanks through Mesopotamia and on into Syria. Before returning laden with plundered treasures, driving their captives before them, they had watered their horses by the Mediterranean sea. Thus, now there were next to no Roman forces for the new Dux Ripae to command.
The specifics of Ballista's instructions, his mandata, perforce revealed the feeble state of Roman power in the east. He was commanded to proceed to the city of Arete, in the Province of 'Hollow Syria' (Coele Syria), atthe easternmost reaches of the imperium. There he was to ready the city to withstand siege by the Sassanids, a siege which was expected to fall the following year. There were only two units of regular Roman troops at his command, a detachment, a vexillatio, of legionary heavy infantry from Legio IIII Scythica of about one thousand men, and an auxiliary cohors of both mounted and foot bowmen, again of about a thousand men. He had been instructed to raise what local levies he could in Arete and to ask the client kings of the nearby cities of Emesa and Palmyra for troops, although, of course, not to the detriment of their own defence. He was to hold Arete until he was relieved by an imperial field army commanded by the emperor Valerian himself. To facilitate the arrival of the field army, he had been further instructed to look to the defence of the main port of Syria, Seleuceia in Pieria, and the provincial capital, Antioch. In the absence of the governor of Coele Syria, the Dux Ripae was to have the full powers of a governor. When the governor was present, the Dux was bound to defer to him.
Ballista found himself grimly smiling at the absurdities of his instructions, absurdities typical of military missions planned by politicians. The potential for confusion between himself and the governor of Coele Syria was immense. And how could he, with the completely inadequate forces allotted him and whatever local peasants he could conscript, while under siege by a huge Persian army in Arete, also defend at least two other cities?
He had been honoured to be summoned to the presence of the emperors Valerian and Gallienus. The imperial father and son had spoken most kindly to him. He admired both men. Valerian had signed Ballista's mandata and invested him with the office of Dux Ripae with his own hand. But it could not be said that the mission was anything other than ill conceived and under resourced: too little time, and too few men in too vast an area. In more emotive terms, it looked much like a death sentence.
In the last, rushed three weeks before leaving Italy, Ballista had found out what he could about the distant city of Arete. It was on the western bank of the Euphrates, some fifty miles below the confluence of the Euphrates and the Chaboras. It was said that its walls were well founded and that, on three sides, sheer cliffs made it impregnable. Apart from a couple of insignificant watch towers, it was the last outpost of the imperium Romanum. Arete was the first place a Sassanid Persian army advancing up the Euphrates would reach. It would bear the full force of an attack.
Such history of the city as Ballista had been able to discover did not inspire much confidence. Originally founded by one of the successors of Alexander the Great, it had fallen first to the Parthians, then to the Romans then, only two years ago, to the Sassanid Persians, who had overthrown the Parthians. As soon as the main Persian army had withdrawn to their heartlands in the south-east, the locals, with help from some Roman units, had risen up and massacred the garrison the Sassanids had left behind. Its walls and cliffs notwithstanding, clearly the city had its weaknesses. Ballista could find what they were when he was on the ground, when he reached Syria. The commander of the auxiliary cohors stationed at Arete had instructions to meet him at the port of Seleuceia in Pieria.
Nothing was ever quite as it seemed with the Romans. Certain questions ran through Ballista's mind. How did the emperors know that the Sassanids would invade the following spring? And that they would take the Euphrates route rather than one of those to the north? If the military intelligence was sound, why was there no sign that an imperial field army was being mobilized? Closer to home, why had Ballista been chosen as Dux Ripae? He did have a certain reputation as a siege commander – five years ago he had been with Gallus in the north at the successful defence of the city of Novae against the Goths; before that he had taken various native settlements both in the far west and in the Atlas mountains – but he had never been to the east. Why had the emperors not sent either of their most experienced siege engineers? Both Bonitus and Celsus knew the east well.
If only he had been allowed to bring Julia with him. As she had been born into an old senatorial family, the labyrinth of politics at the Roman imperial court, so impenetrable to Ballista, were second nature to her. She could have cut to the heart of the ever-shifting patterns of patronage and intrigue, could have blown away the fog of unknowing that surrounded her husband.
Thinking of Julia brought a pang of longing, acute and physical – her tumbling ebony hair, eyes so dark as to appear black, the swell of her breasts, the flare of her hips. Ballista felt alone. He would miss her physically. But, more, he would miss her companionship, that and the heart-melting prattle of their infant son.
Ballista had asked permission for them to accompany him. Refusing the request, Valerian had pointed to the manifest dangers of the mission. But all knew there was another reason for the refusal: the emperors' need to hold hostages to ensure the good behaviour of their military commanders. Too many generals of the last generation had gone into revolt.
Ballista knew that he would feel lonely, despite being surrounded by people. He had a staff of fifteen men: four scribes, six messengers, two heralds, two haruspices, to read the omens, and Mamurra, his praefectus fabrum, chief engineer. In accordance with Roman law, he had chosen them from central lists of officially approved members of these professions, but he knew none of them, not even Mamurra, personally. It was in the natural course of things that some of these men would be frumentarii.
As well as his official staff, he had some of his own household with him – Calgacus, his body servant, Maximus, his bodyguard, and Demetrius, his secretary. That he had appointed the young Greek youth who now sat at his feet to run his headquarters, to be his accensus, would be resented by all the official staff, but he needed someone he felt he could trust. In Roman terms, they were part of his familia but, to Ballista, they seemed a poor substitute for his real family.
Something unusual about the motion of the ship caught Ballista's attention. Its familiar smells – pine from the pitch used to seal the hull, mutton fat from the tallow used to waterproof the leather oar sockets, and stale and fresh human sweat – reminded him of his youth on the wild northern ocean. This trireme Concordia, with its 180 rowers on three levels, its two masts, its two huge steering oars, 20 deck crew and some 70 marines, was an altogether more sophisticated vessel than any longboat from his youth. It was a racehorse to their pack animal. Yet, like a racehorse, it was bred for one thing, and that was speed and manoeuvrability in smooth seas. If the sea turned rough, Ballista knew he would be safer in a primitive northern longboat.
The wind had backed in a southerly direction and was picking up. Already the sea was rising into ugly, choppy cross-waves which were catching the beam of the trireme, making it difficult for the rowers to clear their oars and giving the vessel the beginnings of an uncomfortable lurch. On the horizon to the south, dark stormclouds were building. Ballista now realized that the captain and helmsman had been deep in conversation for some time. As he looked at them, they came to a decision. They exchanged a final few words, both nodded, and the captain walked the few feet back to Ballista.
'The weather is turning, Dominus.'
'What do you recommend?' replied Ballista.
'As our course was to sail due east to rise Cape Acroceraunia and then coast south to Corcyra, as the gods would have it we are roughly midway between Italy and Greece. As we cannot hope to run for shelter, if the storm comes, we must run before it.'
'Take what actions you think fit.'
'Yes, Dominus. Could I ask that you order your staff to move away from the masts?'
As Demetrius scrabbled across the deck to pass the order, the captain again briefly conferred with the
