Key point 1 of 6
A husband who thinks he is free
The novel opens in the mind of Tullio Hermil, who belongs to the comfortable upper class of Rome. He is cultured, restless and proud of his own intelligence. He is married to Giuliana, a gentle woman who has borne him two daughters, Maria and Natalia. Tullio believes that a man like himself should not be bound by the small rules that govern others.
His chief proof of this belief is his mistress, Teresa Raffo. She is a woman of strong appetite and a quick, worldly manner. Tullio has taken up with her openly enough that Giuliana knows of the affair. Yet he tells himself that he has never stopped caring for his wife in a higher and purer way. This is the first sign that he is a man who excuses himself.
The early pages show how he speaks of Giuliana. She is, in his eyes, almost a saint, a patient creature who forgives everything. He describes her goodness with real feeling. But he also treats it as something that belongs to him, a quiet possession that will always be waiting at home.
Pay attention to this opening, because it sets the terms of everything that follows. Tullio is not a simple brute. He is a thoughtful man who has trained himself to turn his faults into virtues. That habit is what makes his later fall so unsettling to watch.
