Rosa Vanozza possessed all the vices and all the virtues of a Spanish courtesan; her devotion to the Virgin amounted to superstition, her fondness for her children to weakness, and her love for Roderigo to sensuality.

In the depth of her heart she relied on the influence she had been able to exercise over him for nearly thirty years; and like a snake, she knew haw to envelop him in her coils when the fascination of her glance had lost its power.

Rosa knew of old the profound hypocrisy of her lover, and thus she was in no difficulty about reassuring Caesar.
Lucrezia was with her mother when Caesar arrived; the two young people exchanged a lover-like kiss beneath her very eyes: and before he left Caesar had made an appointment for the same evening with Lucrezia, who was now living apart from her husband, to whom Roderigo paid a pension in her palace of the Via del Pelegrino, opposite the Campo dei Fiori, and there enjoying perfect liberty.
In the evening, at the hour fixed, Caesar appeared at Lucrezia's; but he found there his brother Francesco.

The two young men had never been friends.

Still, as their tastes were very different, hatred with Francesco was only the fear of the deer for the hunter; but with Caesar it was the desire for vengeance and that lust for blood which lurks perpetually in the heart of a tiger.
