‘Dear God, I am your servant. Grant me the strength to do Your will and not fail. Grant me Your grace and lead me along the paths of righteousness.’

This was where he and Alienor would celebrate their wedding. He still found it difficult to say her name, much less imagine her person. They said she was beautiful, but beauty was in the eye of the beholder. He wished he was home in Paris and safe behind the solid walls of Notre-Dame or Saint-Denis.

At the sound of a fanfare, he turned his gaze down the nave. The columns made a tunnel of golden arches, leading his eye to the brightness of the open doorway. A girl came walking through the light towards him, accompanied by attendants, and for an instant his eyes were so dazzled that the entire group seemed to have a radiance not of this world. She was tall and slender; her deep-golden hair shimmered to her waist but the top of her head was decently covered by a virgin’s jewelled cap. Her face was a pale, pure oval, not overtly feminine, but wrought with a blend of precise strength and delicacy that made Louis think of an angel.

She knelt to kiss the Archbishop’s ring, and once he had raised her to her feet, she set her hand upon his arm and continued down the nave to Louis. ‘Sire,’ she said, kneeling again, and from that position lifted her eyes to his. They were the mutable colour of the ocean, full of truth and intelligence, and Louis felt as if his heart had been set upon an anvil and struck into a different shape with a single blow.

‘Demoiselle,’ he said. ‘I am pleased to meet you and to offer you the honour of marriage so that our great lands may be united.’ The words emerged by rote, because he had been rehearsing them with Suger in his tent for most of the previous evening, sweating in the canvas-intensified heat, the whine of mosquitoes in his ears. Saying them now, he regained a little of his equilibrium, although his heart was still bounding like a deer at full leap.

‘As I am honoured to meet you, sire,’ she replied, lowering her lashes, and then added with a little catch in her voice, ‘and to accept your offer of marriage as my father desired.’

Louis realised she must have been practising too and like him was anxious. He felt relieved, then protective and superior. She was more perfect than he had dared hope. God had answered his doubts and shown him that this was truly meant to be. Having a wife was a natural progression of manhood and kingship, because a king needed a consort. He raised her to her feet and kissed her lightly and swiftly on both cheeks, and then drew back, his chest tight.

She demurely introduced the girl beside her as her sister Petronella. This one was still a child, smaller and brown-haired with a heart-shaped face and a sensuous rosebud mouth. She curtseyed to Louis and, after a single sharp look from bright brown eyes, lowered her gaze. Other than to think that she would make a fine reward for one of his French nobles, Louis dismissed her from his mind to attend to the matter in hand. Turning with Alienor to the altar, he pledged himself in formal betrothal, his hands trembling as he slipped a gold ring on to her right middle finger. And at that moment, he was certain that God had favoured him with such bounty that he was overwhelmed.

A celebration feast had been prepared at the Ombrière Palace. Tables spread with white napery had been arranged in the garden cloister so that guests could sit in the open air, well shaded from the sun, and listen to musicians while they dined.

Alienor smiled and answered when addressed, but she was preoccupied and finding conversation difficult. A huge weight had landed on her with Louis’s arrival and the knowledge that the changes in her life were now irrevocable. There were too many new people to weigh up, all so different in their speech and mannerisms to her own courtiers. They spoke the dialect of northern France, which she understood because it was the common language of Poitou, but the Parisian cadence was harsher on the ear. Their garments were of thicker, more sombre cloth, and they seemed to lack the vibrancy of her people. But then they had been travelling hard in the blistering summer heat, so perhaps she should give them the benefit of the doubt.

Her fears that Louis would be fat and loutish were ungrounded. He was tall and narrow through the hips like a good gazehound. He had glorious, shoulder-length, silver-blond hair and wide blue eyes. His mouth was thin but well formed. She found his manner stilted and rule-bound, but that could be caused by the pressures of the day. He did not smile much – unlike his seneschal, Raoul de Vermandois, who never seemed to stop. De Vermandois was showing Petronella his sleight of hand by hiding a small glass ball under one of three cups and getting her to guess where the ball was. She was giggling at his antics, her eyes shining. The rest of the French party were more watchful and reserved, as if they all had planks stuck down the backs of their tunics. Theobald, Count of Blois Champagne, was eyeing de Vermandois with irritation, a muscle ticking in his jaw. Alienor wondered at the tension between the men. There was so much she did not know, so much she had to take in and assimilate.

At least, even if he was reserved, Louis did not appear to be an ogre, and she could probably find ways of influencing him. It might be more difficult to circumvent the older men, especially Suger and Louis’s uncles Amadée de Maurienne and William de Montferrat, but she had been accustomed to getting her own way with her father, and there would be occasions when she would have Louis to herself with no one to interfere. She was of a similar age to him and that meant they had some common ground.

When everyone had eaten and drunk their fill, Louis formally presented Alienor with the wedding gifts he had brought from France. There were books with ivory cover panels, reliquaries, boxes of precious stones, silver chalices, glass cups from the workshops of Tyre, tapis rugs, bolts of fine fabric. Boxes and chests and sacks. Alienor’s eyes ached at the largesse. Louis presented her with a pectoral cross studded with rubies as red as small drops of blood. ‘This belonged to my grandmother,’ he said as he fastened it around her neck and then stepped back, breathing swiftly.

‘It is magnificent,’ Alienor replied, which was the truth, even if she did not particularly like the piece.

His expression had been anxious, but now he stood tall and proud. ‘You have given me the coronet of Aquitaine,’ he said. ‘It would be a poor thing indeed if I could not gift my bride with the wealth of France in return.’

Alienor felt a frisson of resentment. Although she owed him homage as a vassal of France, Aquitaine belonged to her and always would no matter that he was to be invested with the ducal coronet after their wedding. At least the marriage contract stipulated that her lands were not to be absorbed into France but were to remain a separate duchy. ‘I have something for you also.’ She beckoned, and a chamberlain stepped forward with a carved ivory box. Alienor carefully lifted her vase from its fleece lining. The dimpled rock crystal was cool against her fingers as she turned and presented it formally to Louis.

‘My grandfather brought this back with him from a holy war in Spain,’ she said. ‘It is of great antiquity.’

The vase looked austere and simple when set against the opulent gifts that Louis had given her, but the backdrop only added to its impact. Holding the piece in his hands, Louis kissed her brow. ‘It is like you,’ he said, ‘clear and fine and unique.’ He set it down gently on the table, and immediately a shower of coloured diamonds spangled the white cloth. Louis’s face filled with astonished delight. Alienor smiled to see his response and thought that while he had given her all these rich and heavy things, her gift to him of captured light surpassed them all.

‘May I?’ Without waiting for consent, Abbé Suger picked up the vase in eager hands, his gaze frankly acquisitive. ‘Exquisite,’ he said. ‘I have never seen such fine workmanship.’ He ran his fingers over the carving in tactile delight. ‘See how clear it is, and yet it reflects all the colours of a cathedral window. Truly this is God’s work.’

Alienor suppressed the urge to snatch it from him. Suger was a close friend of Archbishop Gofrid and she ought to be delighted by his admiration.

‘Abbé Suger is fascinated by such items,’ Louis said with a smile. ‘He has a fine collection at Saint-Denis, as you will see when we return to Paris.’

Suger carefully replaced the vase on the trestle. ‘I do not make the collection for me,’ he said with a hint of rebuke, ‘but for the glorification of God through beauty.’

‘Indeed, Father.’ Louis flushed like a scolded boy.

After one sharp glance, Alienor looked down. She had noticed how often Louis glanced at Suger, seeking approval and support. This man could be friend or foe and he had Louis at his beck and call. She would need to tread very carefully indeed.

Later in the afternoon, as the sun cooled on the river and the Ombrière Palace drew on a mantle of deeper, slumbrous shadows, Louis prepared to return to his camp across the river. He had become more relaxed as the day wore on, and he was smiling as he took his farewell of Alienor, setting his thumb over the ring he had given her and kissing her cheek. His lips were silky and warm, and his fledgling beard was soft against her skin. ‘I will visit again tomorrow,’ he said.

Something inside Alienor unclenched and opened. The notion of marrying him had begun to feel more solid – reality, rather than the cloudy haze of a dream. Louis seemed decent enough; he had been kind thus far and he was handsome. Matters could have been much worse.

Embarking to his camp across a sunset river of sheeted gold, Louis raised his hand in farewell and Alienor returned the gesture with a half-smile on her lips.

‘Well, daughter,’ said Archbishop Gofrid, coming to stand at her side, ‘have your fears been allayed?’

‘Yes, Father,’ she replied, knowing it was what he wanted to hear.

‘Louis is a fine, devout young man. I am much impressed by him. Abbé Suger has tutored him well.’

Alienor nodded again. She was still trying to decide whether Suger was ally or foe, no matter that he was Gofrid’s friend.

‘I am pleased you gave him the vase.’

‘Nothing else would match what he had brought to me,’ she said. She wondered if her tutor had brought out the vase from the depths of the treasury with that intention. She firmed her lips. ‘I am glad Abbé Bernard of Clairvaux was not among their number.’

Gofrid raised his brows.

Alienor grimaced. Twice the redoubtable Abbé Bernard had visited her father, on both occasions to harangue him about his support for the opposition during a papal schism. She had only been a small child on his first visit and vaguely remembered him patting her head. He had been as thin as a lance, and had smelled musty, like old wall hangings. The second time, when she was twelve, Bernard and her father had argued violently in the church at La Couldre. It had been at the start of her father’s illness, and Abbé Bernard, with his stabbing bony finger, blazing eyes and eloquent speech threatening the fires of hell, had brought her father to his knees at the altar, and claimed it was God’s judgement on a sinner. Alienor had feared that Abbé Bernard might be among the French ecclesiasts and had been mightily relieved when he wasn’t. ‘He humiliated my father,’ she said.

‘Bernard of Clairvaux is a very holy man,’ Gofrid admonished gently. ‘Above all he seeks the clear path to God and if sometimes he is critical or zealous, then it is for the common good and for God to judge, not us. If you encounter him in Paris, I trust you to act with good and proper judgement as befits your position.’

‘Yes, Father,’ Alienor said neutrally, although she felt mutinous.

Gofrid pressed a light kiss to her brow. ‘I am proud of you, as would your father be if he were here.’

Alienor swallowed, determined not to cry. If her father were here, she would not have to make this marriage. She would be cherished and safe and all would be well. If she thought too hard about it, she knew she would blame him for dying and leaving her this legacy in his will.

In Alienor’s absence the wedding presents from Louis had been moved to her chamber and placed on a trestle for her to examine at leisure. Many items were only in her custody for a brief time; she would be expected to make gifts of them to the Church, or bestow them upon families of importance and influence. There was a reliquary containing a sliver of bone from the leg of Saint James. The casing was of silver gilt, decorated with pearls and precious stones, and a little door of hinged rock crystal opened to reveal a gold box containing the precious fragment. There were two enamelled candlesticks, two silver censers and a box filled with tawny shards and lumps of aromatic frankincense.
