"I didn't even know he had a step-daughter," I whispered, and then: "Theywant you to take her? You mean you have not yet agreed?"

He gave a violent shake of the head. "Not without speaking with you! Even the Emperor could not require that of me. And Maximian remembers you with kindness-he gave me this much reprieve, that I should be allowed to tell you myself, before everything was arranged-" He caught his breath on a sob.

"I vowed my heart's blood to the service of Rome, but not my heart! Not you!" He turned to me at last and gripped my shoulders so hard that the next day I would find bruises there.

I leaned my head against his chest and for a long moment we simply stood, locked together. For more than twenty years my life had revolved around this man; I had wondered sometimes if it was because I had given up so much for him, that I dared not feel any other way. And surely he, with so much more to occupy his mind, must be less dependent on me. But now I realized it was not so. Perhaps because his career had required him to be a creature of mind and will, all his heart was given to me.

"At the end of that river lies the sea," he murmured against my hair, "and across the sea is Britannia. I could take you there, offer my services to Carausius, and to Hades with the rest of the Empire! I have thought about it as I tried to sleep in the posting-houses on the way home..."

"Constantius," I whispered. "This is the opportunity you have dreamed of. All your life you have been preparing to be an emperor..."

"With you by my side, Helena, but not alone!"

My arms tightened around him, and then, like a spear to the heart, the realization came.

"You will have to do it, my beloved. You cannot defy Diocletian-" My voice cracked. "He has Constantine." And with that, the ice that had armoured me cracked suddenly and I wept in his arms.

Night was falling by the time we made our way back home, our eyes swollen with weeping, but for the moment emptied of tears. I drew my palla down and turned my face away when I told my maidservant to have a meal brought to our bedchamber. Drusilla would have known immediately that something was wrong, but Hrodlind was new, a German girl who was still learning Latin.

Constantius and I lay down together on our bed, while the food sat untouched. I had not even removed my palla, for I was chilled to the soul. If I killed myself, I thought numbly, it would be no better for Constantius, but at least I would be spared the pain. I said nothing, but Constantius had been the other half of my soul for too long not to sense what I was feeling, or perhaps it was his own experience that told him.

"Helena, you must live," he said in a low voice. "In every campaign, when danger threatened, it has been the knowledge that you were safe at home that gave me the courage to carry on. I can only do the duty that is being forced upon me now if I know you are still living, somewhere."

"You are unjust. You will be surrounded by people, distracted constantly by responsibilities. Who will there be to need me, when you are gone?"

"Constantine..." The name hung in the darkness between us, my hope and my doom. For his sake I had left my home to follow Constantius, and for his sake we now must part.

We lay together in silence for a long time, while Constantius stroked my hair. I would not have thought that with our spirits so exhausted, the body could make any demands, but after a while, despite my despair, his familiar warmth began to relax me. I turned in his arms, and he brushed my hair back from my face and almost hesitantly, kissed me.

My lips were still stiff with grief, but beneath that gentle touch I felt them softening, and soon my whole body warmed and opened, yearning, one final time, to welcome him in.

In the morning, when I woke, Constantius was gone. On the table he had left a letter.

"Beloved- 'Call me coward if you will, but only thus, when your beautiful eyes are closed in sleep, can I leave you. I will inform the household of the coming change in our situation, so as to spare you the need to explain to them what seems, even to me, to be an evil dream.

'I will be at the Praetorium for a short while, but I think it best, for my peace and yours, if we do not meet again. I am transferring this house to your ownership, with all of the slaves. In addition, my bankers have been instructed that you may continue to draw upon my account for whatever you may need, and if you should desire to move elsewhere, to transfer funds in your name.

'I will communicate with our son, of course, but I hope that you will be able to write to him as well. It will be you for whom his heart grieves, even as, I suppose, loyalty will compel him to congratulate me.

But indeed, he ought to grieve for me as well.

"I hope, if the bounty of your heart allows it, that you will find a way to let me know where you go, and whether you are well. Whatever may befall, believe that while my heart beats, it is yours -".

His usually careful signature trailed off, as if, at the end, his resolve had failed. I let the piece of papyrus fall, staring at the empty bed, the empty room, and an endless, empty succession of days through which I must somehow learn to live, alone.

For the better part of a week I scarcely left my bed, as devastated as I had been after I lost my first child. There was no further word from Constantius, though a badly-spelled note did arrive from Crocus, pledging his continued loyalty. I ate when Drusilla forced food upon me, but I would not let Hrodlind dress my hair, or change the bedding that seemed to me still to bear the impress of Constantius's body and the scent of his skin.

Hylas's silent devotion was the only sympathy I could bear, and I think now that it was the dog's warm body curled against my own and the poke of a cold nose when he wanted to be petted that kept me from losing contact with the outside world entirely. He was white-muzzled now, and moved stiffly when the weather chilled, but his heart was still warm. It would have been so easy, in the first shock of my loss, to retreat into madness. But as long as one creature needed me, as long as Hylas still offered me his unquestioning love, I was not completely alone.

I was not aware of any logic to my mourning, but when Philip came to me one afternoon to tell me that Constantius had departed Colonia for Mediolanum and his wedding, I realized that this was the news for which I had been waiting. Now I was truly alone. It was easy enough, in the end, to dissolve our union.

No negotiations over the return of a dowry were required, for all I had brought to him were my skills as a priestess and my love, which could not be priced; or the custody of children, since our only son was in the keeping of the Emperor. In Rome, we had never truly been married, only in Avalon.

My mind seemed to move very slowly, but eventually I allowed Hrodlind to bathe and dress me, and the servants to come in to clean the room. But I did not leave the house. How could I bear to go abroad, where any pa.s.ser-by might point to the cast-off concubine of the new Caesar, and laugh?

"Lady," said Drusilla, setting down a platter with spring greens dressed with a little olive oil, hot barley cakes, and some new cheese. "You cannot live like this. Let us go back to Britannia. You will be better at home!"

Home is Avalon... I thought, and ,"cannot go there, where I would have to admit before them all that Constantius has abandoned me . But though relations with Carausius's island empire were tense, Britannia and Rome were not yet at war. Ships still sailed across the British Sea to Londinium. Surely there, a wealthy woman could live alone in respectable anonymity.

Philip made arrangements for us to embark from the port at Ganuenta just after the first day of summer.

My first act, when I finally emerged from my chamber, had been to free him and the other slaves Constantius had left to me. Most of those we had purchased to staff the house in Colonia accepted their manumission gratefully, but I was surprised by how many of the older members of my household chose to remain. So it was that Philip and Drusilla and Hrodlind, whose own father had sold her into slavery, along with Decius, the boy who had tended my garden, and two of the kitchen maids, were to take ship with us for Londinium.

On the day before we were to depart, I walked out along the road to the old temple of Nehalennia.

Hrodlind followed, carrying Hylas in a basket, for he could no longer walk so far, yet he whined pitifully whenever he was parted from me.

Perhaps the lichens covered more of the stones, and the tiles of the roof had a more mellow glow, but otherwise the place seemed unchanged. And the G.o.ddess, when I confronted Her inside the temple, gazed past me with the same serenity. It was only I who was different.

Where was the young woman who had made her offerings at this altar, the British tongue still adding its music to her Latin, her gaze apprehensive as she faced this new land? After twenty-two years my speech had flattened, though it was much more eloquent, and it was Britannia which I would view with a stranger's eyes.

As for this temple, how could it be expected to impress me, now that I had seen the great shrines of the Empire? And how could the G.o.ddess speak to me, now that I had lost my soul?

But I had brought a garland of spring flowers to lay before her, and when I had done so I stood with head bowed, and despite my depression, the peace of the place began to seep into my soul.

The temple was quiet, but not entirely silent. Somewhere in the eaves sparrows were nesting, their cheeps and twittering the grace-notes to a deeper murmuring which I eventually identified as the sound of the spring. And suddenly I had no need to descend to those waters, for the sound of them was all around me, an overwhelming sense of Presence that told me the G.o.ddess had entered into her temple and I stood on holy ground.

"Where have you been?" I whispered, tears smarting beneath my closed eyelids. "Why did you abandon me?"

And after a while, as I waited, I sensed an answer. The G.o.ddess was here, as She had always been here, and in the running water, and upon the roads of the world, for those who were willing to be still and listen with their souls. Hylas had poked his head above the rim of the basket and was staring at a spot near the statue with the look usually reserved for me when I came home after a journey. I thought the place was just above the hidden spring.

I turned, lifting my hands in salutation. "Elen of the Ways, hear my vow. I am a wife no longer, and I have been cast out of Avalon, but I will be Your priestess if you will show me what you wish me to do..."

I closed my eyes, and perhaps the sun, descending, chose that moment to shine through the high windows, or perhaps one of the temple servants had brought a lamp into the room, but suddenly I sensed a blaze of light. And though my eyes were still shut, that glow shone into the darknesff that had engulfed my spirit when Constantius left me, and I knew that I would survive.

Londinium was the largest of Britannia's cities, larger than Sirmium or Treveri, if not so great as Rome. I was able to purchase a comfortable house in the northeastern part of the city, near the main road that led out towards Camulodunum. It had belonged to a silk merchant before his trade was disrupted by Carausius's wars, and in this part of the city, there was still enough open land for vegetable gardens and pasture, so that it was almost like being in the countryside.

I settled into the quiet life suited to the widow most of my neighbours believed me to be. I did not trouble to correct them, but made a regular circuit to the baths, the theatre, and the markets. And little my little, my inner turmoil eased. Like a legionary who has lost a limb in battle, I learned to compensate, and even at times to enjoy the things I had without immediately remembering those I would never have again.

From time to time, news would reach us from Rome. Constantius had taken Flavia Maximiana Theodora in marriage at the ides of Maia, a month which was said to be unlucky for marriages. I could not help hoping that in this case the tradition would prove to be true. But if Constantius still mourned for me, it did not prevent him from doing his husbandly duty, for at the end of the year we heard that Theodora had borne him a son, whom they called Dalmatius.

Theodora was not only younger than I, but she appeared to be the kind of woman who gets pregnant as soon as her husband hangs his belt on the bedpost, for after Dalmatius, another son, Julius Constantius, and two daughters, Constantia and Anastasia, were born in quick succession. I never saw Theodora, so I do not know whether she was, as the panegyrists were bound to say, beautiful.

I was now cut off from army gossip, but I could not help hearing talk in the market-place, and the political situation was degenerating. After getting Theodora pregnant, Constantius had returned to the army, and used his new authority as Caesar to mount an attack on Gesoriac.u.m, the port from which Carausius had maintained his foothold in northern Gallia. The naval fortress was impregnable, but by building a mole across the entrance to the harbour, Constantius was able to cut the place off from support by sea, and shortly after mid-summer the garrison surrendered.

His next move was an attack on the Franks who were Carausius's allies at the mouth of the Rhenus.

Trade was already suffering, and now, for the first time, people began to murmur against their upstart Emperor. It was said that his wife Teleri, the one who had been trained on Avalon, had gone back to her father, the prince of Durnovaria. Had she loved her Roman husband, I wondered, or was the marriage a political arrangement from which she was happy to be freed? And if so, had the alliance been made by the Prince of Durnovaria, or the High Priestess of Avalon? Teleri might be the only woman in Britannia who could understand me. I would have liked to talk with her.

And then, just before the feast that begins the harvest, men came crying through the streets with the news that Carausius was dead, and his minister of finance, Allectus, had claimed his throne, rewarding his old master's Frankish auxiliaries richly to support his claim. When it was announced that he would marry Teleri I shook my head. Allectus might call himself an emperor, but clearly he meant to be High King in the old way, by wedding the queen, and with her, the land.

I stood among the crowds who watched them on their way to their wedding feast. Allectus waved with a feverish gaiety, though there was tension in the way he gripped his reins. When the carriage in which Teleri was riding with her father pa.s.sed by, I caught a glimpse of a white face beneath a cloud of dark hair, and thought she looked like a woman going to her execution, not her marriage bed.

Surely, I thought, Constantius would put an end to the pretensions of Allectus soon. But one year pa.s.sed, and then another, with no challenge from Rome. Allectus pressed out an issue of hastily-minted coins and then lowered taxes. I could have told him that short-term popularity might prove a poor trade for repairs to fortifications when the Picts attacked or Rome decided to reclaim its errant province.

But I had taken care that no one should learn my ident.i.ty. Constantine wrote regularly, letters filled with robust good cheer but few personal opinions, as if he suspected someone in the Emperor's household was reading his correspondence. I doubted that anyone was reading mine. It was not unusual to have a son in service abroad, after all. It was not my connection with Constantine that was the danger.

I had not heard from Constantius since he left me, but sometimes I saw him in my dreams and I did not think he had forgotten me. I would have made a valuable hostage, if Allectus had known who was living in his capital.

In the third year since I had come to Britannia, at the beginning of autumn, I had a series of dreams. In the first of them, I saw a dragon that emerged from the waves and coiled itself along the white cliffs of Dubris, guarding the sh.o.r.e. A fox came, and fawned upon it until the dragon ceased to pay attention to it, and then the fox leapt and bit the dragon's throat, and so the great beast died. And now the fox grew great, and decked himself in a purple mantle and a wreath of gold, and rode in a golden chariot about the land.

That dream was not hard to interpret, though I wondered why the G.o.ds had sent me a vision of something that had already come to pa.s.s. Still, I thought that perhaps some change was coming, and sent Philip more often to the forum to hear the news.

The next dream came with more urgency. Across the sea I saw coming two flights of eagles. The first group was driven back by the wind, but the second used mist and cloud to hide its approach and soared to the land. A flock of ravens rose up to combat it, and I saw they were protecting the fox, but the eagles overcame them and killed the fox, and the ravens retreated, shrieking, towards Londinium. Then the first group of eagles reappeared, descending just in time to defeat the ravens once and for all. And when they had done so, a lion appeared among them, and the people came out of the city to greet it, rejoicing.

When I awoke, a storm was lashing the rooftops. Bad weather for sailors, I thought sleepily, and then sat bolt upright with the sudden conviction that Constantius was out in that storm. But he would be safe, if my dream was a true one. It was Londinium which was likely to be in danger if the Frankish troops, whom I had seen as ravens, were defeated and in retaliation attacked the town.

I told Brasilia to lay in enough food to last us for several days. By sunset, we knew that the Roman army was on its way at last. Some said the legions would attack Portus Adurni, where Allectus's fleet was waiting for them, while others thought they would come to Rutupiae and march on Londinium. But if I had dreamed true, Constantius was splitting his forces and would attack both places. That night I slept badly, waiting for what the morning would bring.

Throughout the next day, reports and rumours flew through the city. The storm had driven the Romans back, said some, while others told of an advance north from Clausentum and fighting near Calleva.

Darkness had already fallen when Philip came back from the forum to tell us that a rider had come with the word that Allectus was dead, and his Frankish barbarians, who had taken most of the casualties, were falling back towards Londinium, vowing to make the city pay for their losses.

Philip was all for fleeing, having lived through the sack of a city when he was a child, but so far, all I had dreamed was coming to pa.s.s, and I had faith that Constantius would arrive in time. I had not yet determined what I would do when he did. Could I resist the temptation to see him once more, and if I did so what would become of my hard-won serenity? I went to bed that night as usual, partly to rea.s.sure my household, and somewhat to my surprise, I dreamed once more.

The fox lay dead on the battlefield. From its side rose a black swan that winged desperately through the stormy air, pursued both by the eagles and the ravens. When it settled to earth at last beside the governor's palace, it was the lion that menaced it. But from one of the side-streets appeared a greyhound, that held off the lion until the swan had the strength to make her escape.

When I woke, the first light of morning was filtering through the bed-curtains. From outside I could hear shouting, but someone would have roused me if there had been immediate danger. I lay still, going over the details of my dream until I was sure I could remember it.

When I did rise, I found the household gathered in the kitchen.

"Oh, Mistress," exclaimed Drusilla, "there's been a battle outside the city! Asclepiodotus, the Praetorian Prefect, beat Allectus at Calleva, and here's the Master's fleet come up from Tanatus to save us from the Frankish barbarians!"

He is here-I thought,or he soon will be . I felt my heart beat more quickly, and the wall which had protected me from my memories was beginning to crumble away. If we met, would he still find me fair? I was past forty now, my body grown more solid with time, and there was silver in my hair.

"They are saying that by afternoon his legion will enter the city," said Philip. "The garrison Allectus left here has already fled, and his ministers and clerks and the rest of his household are scurrying about, gathering up their belongings and preparing to be gone before Constantius arrives." He laughed.

But in my dream, I thought then, the swan had been unable to flee. I finished my porridge and set down the bowl.

"Philip, I will want the carriage in an hour, with you and Decius to walk beside it. Bring your sticks to discourage any trouble from the crowds."

His face showed his amazement, but he had learned that commands given in that tone were not open to discussion. A little before noon we were turning out of our gate into the road. The cart was more suitable for country transport, but the top had leather curtains which could be drawn. Through the s.p.a.ce between them I could see that the streets were full of people in a holiday mood. Some were already building an arch of greenery across the main road that led to the forum and adorning it with flowers.

I fingered the fabric of my gown nervously. I had bought it many years ago, because it was almost the blue of Avalon, and for the same reason rarely worn it. My thin woollen palla, of a darker blue, shadowed my face like a veil. Philip had not dared to question me. If we came home empty-handed he would think me mad, though he might doubt my sanity more were we to succeed.

There was no one guarding the gates to the palace. I directed my driver to a side door that I remembered from the one time I had accompanied Constantius on a visit to Britannia, descended, and slipped inside. The corridors showed the signs of a hasty departure.

I made my way swiftly to the suite of rooms that were normally occupied by the Governor, which I suspected Allectus had made his own.

And there, sitting alone in the great bed, half-dressed and staring, I found my black swan.

As I had expected, she was very lovely, with white skin and curling black hair that fell about her shoulders. And not as young as she had looked at first glance, for there were lines of bitterness at the corners of the full lips and shadows beneath the dark eyes.

"Teleri-"

It took a long moment, as if her spirit had been wandering, before she stirred. But her vague gaze focused as she saw the blue gown.

"Who are you?"

"A friend-you must come with me, Teleri. Gather up whatever you would take with you."

"The servants took my jewels," she whispered, "but they were not mine, buthis . I have nothing... I am nothing, on my own."

"Then come as you are, but quickly. The Caesar would do you no harm, but I do not think you would wish to be a trophy of his victory."

"Why should I trust you? Everyone else has betrayed me, even Avalon."

I was glad to see she retained some sense of self-preservation, but this was no time to waver. In the distance I could hear a sound like the surf on the sh.o.r.e and knew that the people of Londinium were cheering. I pulled back my palla so that she could see the faded crescent between my brows.

"Because I too was once a priestess. In the name of the Great Mother of us all, I beg you to come away."

For a long moment we stayed with locked gaze. I do not know what she read in my eyes, but when I held out my hand and turned to go, Teleri gathered up one of the bedcovers for a mantle and followed me.

We were just in time. As my carriage creaked through the gate and turned down the side-road, from the direction of the forum I heard the blare of military clarions and the rhythmic slap of hobnailed sandals. My grip on the wooden seat of the waggon tightened until the knuckles showed white. The people were shouting-the words came clearer as we moved on: 'Redditor Lucis, Redditor Lucis!'

Restorer of the Light...

My closed eyes could not shut out the brightness that was blossoming in my awareness. Constantius was coming, his presence a radiance in my soul. Did he feel that I was near, or were the responsibilities of his office and the tumult around him a sufficient distraction?

As the people of Londinium cried out in welcome to their saviour, my cheeks grew wet with silent tears.

CHAPTER THIRTEEN

AD 296-305.

During the weeks that Constantius spent in Britannia I remained true to my vow and made no attempt to see him, but my self-discipline took its own toll. My woman's courses, never regular, had almost ceased, and now a variety of other symptoms, from a pounding heart to waves of heat that left me drenched as if even my body were weeping, added to my misery.

Meanwhile the city was rejoicing at the word that Theodora had borne Constantius another child. I knew he had been devastated by our parting, but by now he must be appreciating the advantages of a wife who was royal, young and fertile. Prudence, which had kept me out of his sight before, gave way to despair.

The counsels of wisdom I had meant to give Teleri went unspoken. For her sake I had missed even the glimpse of him I might otherwise have had, though at the time I had thought even that much unwise.

Constantine wrote to tell me that he was going to Egypt with Diocletian to fight someone called Domitius who had started a rebellion there, and so to my other troubles I could add anxiety for his safety.
