Who can wonder at her tears? She was being sent to a strange land, far away from the friends she had loved. She was being placed under the dominion of a man about whom she knew nothing. Husbands, of course, are always good and considerate. Just ask their wives. I say no more.

‘Father,’ Constance said, ‘take leave of your wretched daughter. And you, Mother, who has brought me up so tenderly. I have loved you both. You have been most precious to me – more precious than anything, except the Saviour on high. I commend myself to your prayers, now that I am about to depart for Syria. I will never see you again.

‘It is your will that I travel to a barbarian nation. So be it. May Christ, who died for our sins, give me the strength to obey His commands. I am only a weak female. It is no matter if I die. Women are born to servitude and punishment. It is ordained that they should be ruled by men.’

There was never such weeping heard when Troy fell in flames, or when Thebes was taken, or when Rome was wounded by Hannibal. The tears and laments echoed through her chambers. But she had no choice. She was obliged to go.

Oh first mover, outer sphere of heaven, inflexible and cruel! You are the power that moves all things from east to west, that makes the stars revolve in their unnatural course. It was you who put Mars in the ascendant at the beginning of this dangerous voyage. It was you who cast a blight upon the marriage.

Inauspicious ascent, bleak and tortuous in effect! Unhappy Mars must fall out of his place into the darkest house of all, the house of Saturn. Oh feeble moon, of unfortunate fate! You move into a place where you are not welcomed. You are banished from your blessed haven. Such are the movements of the spheres.

And as for you, imprudent emperor of Rome, Constance ’s father, was there no wise man in the city? Is one time no better than another in Rome? Surely you had an astrologer in your court who could have determined the proper moment for such a voyage? Was there no one who could cast Constance ’s horoscope? Or are all the Romans stupid or slow-witted?

So the woeful maid is conducted to the ship with every formality and every ceremony. ‘Jesus Christ be with you all,’ she cried out from the deck. And the crowd shouted out, ‘Farewell! Farewell Constance!’ They had no more to say. She tried to maintain her composure, but it was difficult. Now I must leave her on the high seas and return once more to Syria.

The mother of the sultan, a woman who was a pit of vice, knew all about her son’s intentions; the sultaness had heard that he was about to abandon his old religion. So she sent for her own privy council. They gathered in the palace according to her instructions, and when they were all assembled together she told them her plan.

‘Lords,’ she said, ‘you all know well enough that my son is about to turn away from the laws of the Koran, vouchsafed to Mahomet by God Himself, and to do great dishonour to our holy religion. But I make my vow, before you all, that I would rather die than disobey the least one of our religious laws.

‘What will happen to us if we accept this new dispensation? We will be the slaves of Rome. But that is not the worst of it. If we renounce Mahomet, we will be consigned to everlasting torment. No. It cannot be. But, my lords, I have a plan. Will you follow me in the enterprise I am about to reveal? Assuredly it will save us all.’

They assented, and swore an oath that they would all live or die by her side. They would persuade all of their friends and colleagues, too, to support and protect her. So, assured of their fealty, she began to describe to them the scheme that she had contrived.

‘First of all,’ she said, ‘we will pretend to embrace the false religion. A little baptismal water will not affect us. I will then throw such a feast and festival that the sultan will be paid back in kind. This heathen girl may be as white as the day she was baptized but, by the time I have finished with her, she will need more than holy water to wash away the blood. A Christian font will not be enough.’

Oh sultaness, root of iniquity! You are a harpie, unnatural and accursed. You are a reptile with a woman’s face, as wicked as the serpent who lies coiled in hell. You are false and fraudulent, confounding good and evil with your malice. You are a nest of vices.

Dreadful Satan, you have been watchful and malicious ever since you fell from heaven. You know how to entrap women. It was you who tempted Eve, the source of all our woe. Now you wish to destroy this Christian marriage. And what will be the instrument of your guile? Alas it will be another woman.

I will get on with the story. So the evil sultaness, having dismissed her council with an oath of secrecy, rode out to visit her son. She informed him that she was willing to renounce her faith, and receive baptism at the hands of the Christian priests. She was sorry, she said, that she had remained a heathen for such a long time!

Then she asked permission to organize a great feast for the visiting Christians. ‘I will do everything in my power,’ she said, ‘to make them welcome.’

‘It shall be done as you wish,’ he replied. Then he kneeled down before her and thanked her for her thoughtfulness. He was overcome.

She kissed her son, and went on her way.

So, after a long journey by sea and land, the Christian legation eventually arrived in Syria. They were an impressive gathering of dignitaries. As soon as the sultan heard of their approach he sent a message to his mother, telling her that his new wife had come and urging her to welcome Constance nobly for the honour of the realm. He also announced the news to the rest of the country.

The throng was great, and the show very splendid, when the Syrians and the Christians finally greeted each other. The sultaness could not have been more charming or more gracious in her greeting to them all. She was especially nice to Constance, whom she received as tenderly as any mother would receive her favourite child. So they proceeded slowly towards the city, riding side by side in perfect amity.

I know nothing about the triumphal processions of Julius Caesar, except for the description in Lucan’s Pharsalia. But I do not suppose that they were any more rich, or more spectacular, than the procession of Constance into Damascus. Yet this was the time when the scorpion of Syria, the wicked demon of the royal family, was preparing herself. The sultaness, for all her smiles and gracious words, was getting ready to use her deadly sting.

The sultan himself then rode out to greet his bride with great fanfare and display. He welcomed her with joy, and wonder, at her beauty. So, for the time being, I will leave them to their happiness. I will come soon enough to the heart of the matter. The rest of the day was spent in revelry and sport, until the company agreed that it was time to rest.

Then the moment arrived for the banquet that the sultaness had organized. All of the Christians, young and old alike, were invited to attend. All the guests would be able to enjoy royal luxury, and to feast upon the most rare and delicate foods in the world. And yet, alas, they soon paid too high a price for them.

Woe is always the consequence of bliss. Sorrow follows prosperity, and suffering succeeds joy. That is the way of the world. Follow this advice for the sake of your well-being. If you ever experience happiness, keep in mind the day when it will end. Nothing abides.

I will be brief. While they were at this feast all the guests, Syrian and Christian, were stabbed or cut to pieces. All of them were killed, with the exception of Constance herself. And who do you think had murdered them? The sultaness, of course, together with her henchmen. The old hag wanted to rule the country alone. She had even murdered her own son.
