hallways to a tower, where they climbed the stairs to the highest room, a small chamber containing only a bed and a single chair. Once they were inside, the guardsmen closed the heavy door behind them. Helena motioned for Demetrius to sit. She remained standing.
'If I were not your mother, you would already be dead.'
'Mother, I…'
'Silence,' Helena snapped. 'I do not wish to hear my son beg. Now, who aided you in this treason?'
'No one, Mother.'
'I know you, son. You did not plan this treachery; it is beyond you. Who then? Gennadius?'
'No.' Demetrius did not trust himself to say more. He swallowed. Helena was watching him closely, her face only inches from his own.
'Notaras?'
'No,' Demetrius said again.
Helena turned away from him, her head nodding slowly. 'They were wise to keep their distance,' she said. She sighed, and her shoulders slumped, making her look suddenly old and tired. 'Why must our best men be always pitted against us?' Then, she straightened, and when she turned back to Demetrius, Helena was once more regal, in command. Her voice was like ice. 'Swear upon your life that when your brother arrives, you will hail him as emperor.'
'I swear it.'
'Good. I will hold you to your oath. In the meantime, you will be confined to this room. If you attempt to escape, I will have your tongue and eyes removed, and you will spend the rest of your life locked away in a monastery. Do you understand?'
'Yes, Mother.'
'Good.' Helena stepped forward and took Demetrius's head in her hands. She kissed him softly on the forehead. 'Welcome home, my son.'
Helena moved to the door and knocked softly. It swung open and she left. The door closed behind her with a thud, and Demetrius heard a metallic rasp as the bolt slid to. He turned and stared out the window, watching the rain pool in the streets. His short reign was over.
JANUARY 1449: MISTRA
On 6 January, the eve of the Orthodox Christmas, Longo stood at the front of the Church of Saint Demetrius in Mistra, capital of the Morea, and waited for the entrance of the man who was to be crowned Constantine XI, Emperor of the Romans. A vast crowd of nobles and dignitaries had filled the church. Longo was on the first row, squeezed shoulder to shoulder between the emperor's bodyguard, John Dalmata, and a short, portly Greek official who kept elbowing him in the ribs. The rich dress of the crowd — a profusion of silk dalmatics, belted robes with wide sleeves and collars embroidered with gold — was in sharp contrast to the rank odour that came from so many overheated men and women in close proximity. The smell was made even worse by the attempt of some to mask their stink with cloying perfumes. Longo breathed shallowly and reminded himself that it was a great honour to have been invited to the coronation.
A muffled roar, as of waves crashing on a nearby shore, came from outside the church as the crowd of commoners surrounding the building caught sight of Constantine. Longo turned with the rest of the crowd to face the church doors. He was curious to see this new emperor, the man who would be responsible for defending Constantinople against the Turks. Outside, the roar of the crowd grew louder and louder, and then the doors of the church swung inward. The sweet smell of incense filled the air as two rows of young men swinging silver censers on long chains passed through the doors. Constantine followed, wearing plain white garments, white shoes and white gloves. He was tall and thin, with tanned skin and a strong, handsome face. His hair and beard were both neatly cut and startlingly white, but Constantine was no old man. At forty-four, he had maintained much of his youthful vigour, and he walked down the central aisle with a determined stride and his head held high. He mounted the steps leading up to the dais that had been erected before the altar, and turned to face the crowd. Close up, Longo could see that he had kind, grey eyes.
'I swear to uphold the one true, unified Church and to protect the faith,' Constantine said, his deep voice steady and solemn.
'God will preserve a Christian emperor!' the crowd responded in unison, although Longo noted that some around him kept silent. Constantine's policy of union between the Catholic and Orthodox churches was not popular.
'I swear to defend, with my blood and my life, the empire that God has granted me.'
'Lord help the pious!' the people replied. 'Holy Lord uplift Thy world!'
'I swear to rule justly, the shepherd of my people,' Constantine concluded.
'These are common prayers. God be with you!' the crowd chanted.
Constantine turned his back to the crowd and knelt before a frail old priest dressed in scarlet robes — the metropolitan of Mistra. The metropolitan held his hand over Constantine and began to speak: 'O Lord, Our God, the King of Kings and Lord of Lords, behold from Thy dwelling place Thy faithful servant Constantine, whom Thou hast been pleased to set as king over Thy holy nation, which Thou didst purchase with the precious blood of Thine only begotten Son.' At this point, two dignitaries draped a scarlet silk mantle over Constantine's shoulders. 'Vouchsafe to anoint him with the oil of gladness and endue him with power from on high,' the metropolitan continued as he anointed Constantine with oil, making the sign of the cross on his forehead.
'Put upon his head a crown of pure gold and grant him long life,' the metropolitan concluded. A young acolyte brought forth the crown of the empire — a thick band of jewel-encrusted gold, topped by a lattice-work of gold filled with whitest ermine. The metropolitan reached to take the crown from the acolyte, but he was old and the crown heavy. As the crowd watched in horror, the metropolitan fumbled and then dropped the crown, which rolled down the steps to the foot of the dais.
'God save us!' the fat official next to Longo gasped. 'A terrible omen!' The metropolitan had frozen, his face pale. People began to whisper, and someone cried out that this foretold the fall of the empire. He was immediately silenced, but the whispering grew louder.
Constantine stood and turned to face the crowd, which fell silent. He descended the steps and picked up the crown, lifting it high for all to see. 'I place my trust in God and steel, not in omens,' he declared and placed the crown upon his own head. 'May God grant me the wisdom to rule with justice and the strength to guard with steel the empire of my fathers!' The crowd cheered, and Longo with them. Any doubts that he had had regarding Constantine were gone. This was an emperor for whom Longo would be happy to fight.
Gradually, the cheering resolved into the ritual words that greeted the crowning of each new Roman emperor: 'Holy, holy, holy! Glory to God in the highest and on earth, peace!' The standards of the many nobles in the hall dipped in honour of the new emperor, and the gathered nobles and priests knelt and then prostrated themselves. Longo knelt, but he did not prostrate himself. He was a lord of Genoa, and while he honoured Constantine, he would not grovel on his belly for any man. His head held high, Longo caught the emperor's eye. Constantine nodded solemnly in Longo's direction, and then strode from the church, followed by the metropolitan and the incense bearers. Constantine Dragases was now Constantine XI, Caesar Augustus, king faithful in Christ, Emperor of the Romans.
Outside the church, Longo followed the shuffling crowd back to the courtyard of the palace. Through the thick crowd he could just make out Constantine, sitting on a throne placed in the centre of the courtyard. He sat straight-backed, smiling often, as a continual stream of men passed before him, kissing his knees and pledging their fealty. Longo joined the procession, and soon he stood before Constantine. He stepped forward and bowed low before the emperor. 'Congratulations, Emperor Constantine. On behalf of the people of Genoa, allow me to be the first to offer our friendship and goodwill.'
'Thank you, Signor Longo. Your presence honours me,' Constantine replied. 'And thank you for transporting the crown and my mother's ambassadors aboard your ship. Without you, I would not have been crowned today. You will be my guest at the feast tonight. I shall set a place at my table for you.'
'You are too kind, Emperor,' Longo said. 'But I must decline. I have been too long gone from Genoa, and I am eager to return. I will start back this very day.'
'Well then, I wish you well on your voyage. You will always be welcome at my court.'
'Thank you, Emperor,' Longo replied, bowing low again. 'My sword will always be at your service. If you are
