Their evident affection for each other was ere long noticed by Lucrezia's husband, the Duke Alphonso of Ferrara, in whose breast jealousy was quickly roused to such a pitch that he vowed vengeance upon the pair, and eagerly watched for an opportunity of satisfying his wrath.

The young Duke Orsini and his companions were also greatly disturbed by their young friend's infatuation for one of the hated Borgia family; and they did all in their power, by means of scoldings and taunts, to draw him away from Lucrezia's wiles, knowing only too well that such an intimacy would certainly end disastrously for the young man.

But Gennaro, who felt himself attracted by some mighty force towards the beautiful woman who showed such tender affection for him, although unable to define the feeling he had for her, continued his new intimacy in spite of the warnings of his friends; yet at times their taunts stung him bitterly, for he knew well the evil character which Lucrezia had earned for herself, and he would then despise himself for allowing her to exercise such a strange fascination over him.

On one such occasion as this, having met with his friends in the public square in front of the Borgia Palace at Ferrara, and being taunted by them more bitterly than usual, he gave vent to a passionate outburst of anger against Lucrezia; and, heedless of consequences, he dashed up to the palace door, and recklessly struck off the first letter of her name with the short dagger he wore.

This rash deed was observed by the Duke of Ferrara himself, who at once ordered his attendants to make the young man a prisoner and hold him in the palace. He then caused the defacing of the family name to be made known to Lucrezia, who, unaware that the deed had been committed by Gennaro, and only feeling rage at the insult, demanded that the culprit should be seized and put to death; and the Duke, gloating over the chance that had at last put his supposed rival in his power, declared that her wish should be immediately carried out, and ordered the prisoner to be brought into the room for sentence.

Then, when Lucrezia saw that it was her own beloved son whom she had thus so carelessly condemned to death, she was filled with dismay and horror, and at once began to plead with her husband for his life.

But the Duke remained obdurate, and furiously denounced Gennaro as her lover, who should now die in her presence; and, in spite of the frantic woman's entreaties and passionate tirades, the most he would grant was that she should choose the mode of his death.

Lucrezia was for the moment filled with despair, not daring to vindicate herself by revealing her true relationship to Gennaro; but, suddenly, her quick wit devising a way out of the difficulty, she declared that she was willing for the prisoner to die by drinking a draught of the famous poisoned wine of the Borgias.

The Duke, well pleased that his own strong will should have, as he supposed, conquered the proud spirit of his wife, triumphantly produced a cup of poisoned wine, which he handed to the unfortunate Gennaro, compelling him to drain it to the last drop; and then, with a mocking laugh, he left the pair to take a last farewell of each other. But he had forgotten for the moment that the Borgias had the power to cure as well as to kill with the subtle poisons they used; and when he had departed, Lucrezia hastily produced an antidote to the fatal draught which Gennaro had just taken, so that the young man, by swallowing this, was thus saved from an untimely end.
