"One thing only," wrote Messer Galeazzo, "was wanting to our pleasure, and that was the sweet company of yourself, fair Madonna Marchesana." And with a sigh he tells her how much she is missed in the Castello of Milan, and how often he wishes he could find her in Madonna the Duchess of Ferrara's rooms, having her long hair combed and curled by her favourite maidens Teodora and Beatrice and Violante, to all of whom he sends courteous greeting. Then he returns to the old controversy over Orlando, and replies to a gay challenge which Isabella has sent him in a letter to Signor Lodovico, only wishing she were here to defend Rinaldo in person, or rather to be made to own the error of her ways, and to confess that the knight of Montalbano is not to be compared to Roland! But he warns her that if she perseveres in this heresy, he will draw up such an indictment of Rinaldo's faults as will fill her with confusion, and make her recognize with shame his inferiority to Roland, that baron of immortal fame, of whom nothing but good can be said. Isabella, however, stuck to her colours, and, a whole month later, Messer Galeazzo sent her a long letter from Vigevano, in which he drew up an elaborate parallel between the conduct of the two paladins, as recorded in Boiardo's poem, and ended with a splendid eulogy of Roland.
"Roland the most Christian! Roland the pure and strong, prudent, just, and merciful servant of Christ, the true defender of widows and orphans! Of his valour I will say nothing, this being known to all the world; but this I say, that when I think of my worship for Roland, however sad and ill disposed I may be feeling, my heart rejoices, and I become glad of heart and joyous again."
So he begs her, for the love that he bears her Highness, to try and amend her ways and recant her errors, and do penitence in this Lenten season for her fault, after the example of the great apostle St. Paul, who was converted to the Christian faith, and became an elect son and mighty preacher of the gospel, bringing many to righteousness and enjoying the high favour of our Lord God. For Roland, the Marchesa may know for certain, has his place in Paradise with the saints, "and in serving him you will be serving God; but if, on the other hand, you persevere in your false opinions, you will find that you are serving the devil, who accompanied Rinaldo both in his life here and afterwards in his death. And remember," he adds in conclusion, "when the blind lead the blind, both fall into the ditch!"
Nothing daunted by this long harangue, Isabella retorted in an equally lengthy epistle, flatly denying the charges brought against Rinaldo as false and unsupported by a tittle of evidence. Galeazzo replied in another bantering letter, assuming the part of a priest, and exhorting the fair sinner to confess her faults in these holy days of Passiontide, lest she should incur greater damnation, and drive her soul into the devil's jaws.
"And since this is the hour of penitence and contrition," he concludes, "I would once more beg and pray your Highness to return to the true faith and devotion of Roland, having before your eyes the good example of our most illustrious duchess, your sister, who has acknowledged her errors, and become a sincere follower of Roland, as a good Christian, and is now gone to Milan to obtain pardon.
"Your most humble and devoted servant,
Galeaz Sfortia Vicecomes,
Armorum Capitaneus.[11]
Vigevano, 30th of March, 1491."
Isabella, however, still remained obdurate, declaring that on no account would she follow Beatrice's changeable conduct, and was ready to defend her hero against a hundred thousand opponents. Upon which Galeazzo reminded her that, for all her boastings, she had been constrained to yield to his single-handed efforts in the park at Pavia, and had ended by taking up his cry of "Roland." The more pity that she should turn her back upon the good cause now, and prove the inconstancy of woman's nature! But he consoled himself by reflecting that the Marchesana would soon be back at Milan, when he would easily be able to make her give up Rinaldo, and once more cry "Roland" as she had done before.
This letter was written by Galeazzo on the 13th of April, after which the subject dropped for a while, until it was revived by a visit which his brother, Gaspare Fracassa, paid to Mantua in the summer with his wife, Margherita Pia, a great friend of the Marchesana and Duchess of Urbino. Isabella could not resist the opportunity of returning the charge, and sent Messer Galeazzo, by his brother's hands, a challenge to battle, couched in approved terms, and indicating her choice of arms and of the scene of action. Galeazzo replied in the most courteous language, declaring himself absolutely at the service of his fair challenger, and assuring her that her coming is awaited with the utmost impatience by Signor Lodovico, the Duchess of Bari, and her humble servant.
Meanwhile Isabella prepared herself for the fray by collecting all the information on the subject that she could possibly obtain. In that same month of August, when Galeazzo sent her the last-named letter from his villa at Castelnuovo, near Tortona, the Marchesana wrote to the Mantuan ambassador at Venice, desiring him to send her all the poems and romances concerning French paladins at the court of Charlemagne which he could discover. At the same time she addressed a letter to her old friend, Messer Matteo Boiardo, at Ferrara, requesting him to send her the concluding cantos of his poem, the "Orlando Innamorato," which had not as yet been given to the world. The poet replied that, to his great regret, he was unable to comply with her wish, since the cantos in question were not yet written; and Isabella could only beg him to let her have a copy of the two earlier books, in order that she might refresh her memory by reading them once more.
