“Firstly, I can build bridges, which are light and strong and easy to carry, so as to enable one to pursue and rout the enemy; also others of a stouter make, which, while resisting fire and assault, are easily taken to pieces and placed in position. I can also burn and destroy those of the enemy.

“Secondly, in times of siege I can cut off the water supply from the trenches, and make pontoons and scaling ladders and other contrivances of a like nature.”

Seven other paragraphs follow, explaining contrivances for ensuring success in warfare by land or sea. It was only at the end of the tenth that he touched upon less military matters. Then he wrote: “In times of peace, I believe that I could please you as completely as any one, both in the designing of public and private buildings, and in making aqueducts. In addition, I can undertake sculpture in marble, bronze, or clay. In painting I am as competent as any one else, whoever he may be. Moreover, I would execute the commission of the bronze horse, and so give immortal fame and honour to the glorious memory of your father and the illustrious house of Sforza.”

Leonardo had painted Cecilia Gallerani for Ludovico before the time of Beatrice’s arrival, but, as far as one knows, never painted Beatrice. Mrs. Cartwright suggests, and the opinion has been repeated elsewhere, that the reason for this sprang from Beatrice’s jealousy of the beautiful woman who had preceded her. But this is not in keeping with her nature. Beatrice loved all beautiful pictures, and was far too intuitive not to know that if any one could give her portrait beauty, Leonardo was that man. Whatever strangeness exhaled from within he would have drawn upon the surface. That he should never have painted her is extraordinary, but, at the same time, it is absolutely certain that he would never have felt any inclination to. Leonardo did not care for any woman’s face that could look happy and be satisfied with that mere possession. And the Regent’s wife had no withholdings in her expression, and no subtleties, save perhaps the subtlety of audacity and laughter.

Presently Beatrice gave birth to a son, and whatever sinister thoughts had ebbed and flowed in Ludovico’s brain before, now became permanent and concrete. Beatrice’s confinement was in itself the first open threat at Isabella. The arrangements for the child’s arrival were a menace in their unfitness. A queen’s son could not have been received into the world with more elaborate ceremony. The layette and cradle were exhibited to ambassadors as if a future monarch were being waited for. The cradle was of gold, its coverlet of cloth of gold. With no restraint as to cost, three rooms had been decorated—one for the mother, one for the child, and one for the presents, which poured in every hour. The boy was no sooner born than public rejoicings were ordered. Bells were rung for six days, processions were held, prisoners for debt were released, and ambassadors, councillors, and all important officials entered to congratulate the slender girl in her magnificent bed, with its mulberry and gold coloured hangings.

At the court of Giangaleazzo meanwhile Isabella must have felt as if bitterness stifled her—bitterness and the sick despair of any creature conscious suddenly that it is trapped. Everybody remembered that when the real heir to the duchy had been born two years before, there had been less extravagance and formality than for the entry of the Regent’s infant. And when a week later Isabella also went to bed and brought a second child into the world, the torture of the body must have been little in comparison to the torture of the mind that knew its children already marked out for disinheritance. Even her confinement became a convenience to Ludovico, who was able to inform the ambassadors that the rejoicings were for a double joy, though the statement was not made with any intention to deceive. The thin end of the wedge had been driven in, and Ludovico desired men to grow prepared and seasoned for what would one day be thrust upon them as an accomplished policy.

When both duchesses had recovered, ceremonies of thanksgiving were organized. They drove together in wonderful clothes and as part of a gorgeous procession to the church of St. Maria della Grazie. Beatrice may have uttered some light gratitude as she knelt, but to Isabella the day must have been a burning anguish, wearying to the very fibre of her nature. She and Beatrice sat side by side, and their dresses were almost equally extravagant. The public only saw two bejewelled and magnificent figures, but one of the two women already hated the other, with a heart swollen by the wrongs she did not dare to utter.

From this day forward Isabella’s life is ill to think of; for Ludovico’s plans were soon no longer secret. The King of the Romans was to marry his niece—Giangaleazzo’s sister—and to receive with her an immense dowry. In return he was to give Ludovico the investiture of Milan. On paper this change of dukes did not read as a flagrant usurpation. Giangaleazzo had been cleverly thrust into the position of sinner. It was seemingly abruptly discovered that he had no right to the dukedom at all without the consent of Maximilian. The Viscontis held it in fief from the empire. When they died it should have passed back into the keeping of Germany. The duchy belonged to the emperor, and the Sforzas holding it on their own authority made them nothing less than adventurers. Il Moro, confirmed as duke by the King of the Romans, would possess the duchy upon legal and unimpeachable grounds, and have only dispossessed therefore a creature without any rights to hold it at any time, and incapable into the bargain.

Isabella fought with an impassioned fury for her child and her position. It was brave, heart-rending, and useless. Giangaleazzo could not be made even to understand Ludovico’s treachery. In a fit of temper he could beat his wife, as a child strikes what offends it. But he could not grasp any more than a child that a person, who had never given it an unkind word, should nevertheless intend to do it evil. Sometimes driven beyond control, Isabella would fix the story of Ludovico’s coming usurpation into his wandering attention. For a moment her burning phrases stimulated some dim perception. But presently Ludovico and the boy would meet, and Giangaleazzo, in reality bewildered and helpless without the support of this capable, pleasant relative he had leant on since infancy, would blurt out all his wife’s accusations and come back to her soothed into the implicit faith of before. Not a soul that would, had the capacity to help her, whilst the crowd had gone over to the light-hearted, triumphant duchess who was stepping remorselessly into her place.

Of all the women of the Renaissance there are none more piteous and more innocently forlorn than this girl Isabella, married to the futile son of a madman and pitted against the unrighteous cravings of a Ludovico. He and Beatrice between them made her life a nightmare, but they never abased her courage. The letter to her father, given by Corio as hers, but generally looked upon as worded by the historian, shows the noble fierceness that ran through her body. In burning phrases she laid bare the unjust misery of her position. Giangaleazzo was of age, and should have succeeded some time back to the duchy of his father. But so far was this from being the case that even the bare necessities of existence were doled out to them by Ludovico, who not only enjoyed all political power, but who kept them practically both helpless and unbefriended. The bitter hurt she endured through Beatrice came out in the mention of the latter’s son and the royal honours paid to him at birth, while she and her children were treated as of no importance. In truth she added—and there is something so hot, so passionately and recklessly sincere in the whole letter that it is difficult to believe that anybody but Isabella herself wrote it—they remained at the palace in actual risk of their lives, the deadly envy of Ludovico aching to make her a widow. But her letter, for all its despair and anger, was imbued with an unbreakable spirit. When she had laid bare the danger, the loneliness, and humiliation of her position, explaining that she lacked even one soul she dared speak openly to, since all her attendants were provided by Ludovico, she closed with a brave and defiant statement that in spite of everything her courage still endured unshaken.
