Meanwhile love, true love, had peeped through the jalousies of Princess Maria’s window, and his arrows had fled their dangerous course unseen by any but herself, and him whose heart was hers. No one suspected that a life so guarded could, by any means, be filched from its restraints; but so it was, and the first gossip sprang out of the mouth of a venerable Spanish retainer of the Duchess, the faithful custode, Mandriano, who guarded his mistress’s door almost night and day.

Traversing one day an unfrequented part of the gardens of the Palace on the Hill, the old fellow thought he heard voices, and, approaching a grove of laurels, he descried the young Princess in the arms of Malatesta de’ Malatesti!

The Duchess was furious when Mandriano told her, and immediately conveyed the portentous news to her husband. Cosimo reflected long and acted warily, for he made no move for many days. Stealthily he tracked the unsuspecting lovers to their trysting-place. Mandriano’s story was quite correct.

He summoned the two young people to his private closet, he acquainted them with the fact that the liaison could not continue, and ordered Malatesta to prepare for immediate imprisonment—with the loss of all his honours and the confidence of his Sovereign. The boy pleaded in vain, and testified to the innocence of the love-making without effect, except to raise the Duke’s anger to a dangerous pitch. Maria threw herself at her father’s feet and appealed for mercy for her lover, asking that the parental vengeance should fall on her and not on Malatesta.

“That you shall have, base child of mine,” Cosimo cried in a fierce tone; “see, you shall have the justice of a Roman father!” Then, plucking out his poignard from its hidden sheath, he stabbed his child to the heart! Drawing forth the gory weapon, he flung it at the head of the despairing youth, and, throwing his cloak around his shoulders, rushed out of the chamber slamming-to the door!

Malatesta must have fallen in a deadly swoon across the lovely form of his innamorata, incapable of speech and action, for, there they were found, both apparently dead, by brethren of the Misericordia, who had been summoned by the Duke. Malatesta was thrown into prison, and there he languished for seven long years, without anyone knowing of his existence. His parents had asked Cosimo repeatedly about the boy, but no answer was ever given—the Duke having forbidden the subject to be named.

To the Duchess he prevaricated and hinted that the sudden death of the child was due to the malignant spotted fever, and that he had given personal instructions for the immediate removal and interment of her body. The brethren of the Misericordia might have enlightened the grief-stricken mother, only they were sworn to secrecy; they knew how the beauteous young girl had died. They laid her fair body to rest in a grave unknown even to her father, and not among her people in San Lorenzo.

Cosimo moved the Court immediately to Livorno, and thence to Pisa, and there they kept their Lenten fast in strict seclusion. There was universal grief in Florence where the unhappy Princess, though rarely seen in public, had become the favourite of the people, through her fresh young beauty and by what was known of the sweetness of her character and the brilliancy of her attainments.

Duchess Eleanora and her children mourned piteously for lovely Maria: there seemed to be no solace for their grief. As for the Duke, he was a changed man, the bitterness of remorse had turned his natural reserve into moroseness. He was like one beside himself, his wonted firmness and self-control, at times, failed to stay him, and he preferred to shut himself up alone in one of the towers of the castle at Livorno, venting his passionate despair in fits of weeping and in abject cries of self-reproach.

No one dared to go near to him, for to all who presumed to intrude upon his woes he was like a lion roused. That ever ready secret blade might be whipped out to another’s undoing! Still, in calmer moments he reflected, as Muzio has suggestively written: “Maria was very beautiful, as beautiful as any child of earth, most courteous and gentle, her seriousness compelled everyone to respect her, her sprightliness, to love her. She was pleasing to Heaven, whither she had gone sinless to reinforce the angelic choir, and to wear the most fragrant coronal of roses among the companies of holy virgins.”
