Italian Letters, Vols. I and II

In Short

Written in a series of intimate, high-toned epistolary exchanges, this novel follows the tragic unraveling of a friendship between two noblemen across Naples, Sicily, and Spain. The high-minded Count de St. Julian leaves his secluded life in Palermo to rescue his wealthy friend, the Marquis of Pescara, from the temptations of urban vice. However, financial errands abroad, diplomatic machinations, and intercepted mail allow a insidious third party to warp their bonds. Suspicion quickly hardens into murderous betrayal, illustrating how vulnerable even the most rigid moral philosophy remains when pitted against calculated deceit and unbridled emotion.

The Story

The story opens with the Count de St. Julian offering counsel to his dear companion, Rinaldo, the young Marquis of Pescara. Following the death of his indulgent father, Rinaldo moves from Palermo to the alluring, high-society world of Naples. St. Julian, acting as a devoted mentor and moral compass, writes to warn his friend against the corrupting influence of the city’s elite, particularly the polished and eloquent Marquis of San Severino. Despite Rinaldo's confident claims that his virtue is unassailable, he quickly falls under San Severino’s spell, partaking in urban gallantry and abandoning his former simplicity.

When word reaches Rinaldo that St. Julian has suffered a sudden loss of family fortune and retired to Leontini, Rinaldo experiences a profound wave of remorse for having dismissed his mentor's advice. Leaving Naples behind, Rinaldo seeks out St. Julian in Sicily, seeking to make amends and offer his vast wealth to support his friend. Reunited, St. Julian opens his heart to Rinaldo, confessing his deep, unspoken love for the immaculate Matilda della Colonna. The romance between St. Julian and Matilda flourishes with the blessings of her dying father, the Duke of Benevento. However, before they can wed, St. Julian feels duty-bound to voyage to Spain to resolve a pressing legal dispute involving the Pescara family's vast estates in Castile.

While St. Julian is delayed abroad, navigating the cold, formal court of Madrid and undertaking additional legal errands in Zamora, a web of treachery closes around him. San Severino works quietly to sever the lovers' connection, while Rinaldo’s own latent desires begin to supplant his loyalty. Through suppressed correspondence, manipulated silences, and false reports of abandonment, Matilda is led to believe that St. Julian has forsaken her for distant pursuits. Heartbroken, vulnerable, and yielding to propriety and social pressure, Matilda is persuaded to give her hand in marriage to Rinaldo instead.

When St. Julian finally learns of this betrayal, his philosophical composure shatters into violent anguish. Refusing to bear the injury with silent fortitude, he returns to confront his former friend. St. Julian challenges Rinaldo to a formal duel. Despite the efforts of onlookers to reconcile them, both men draw their swords, and St. Julian runs Rinaldo through the heart, killing him instantly on the spot.

Refusing to flee from the law, St. Julian surrenders to the authorities, glorying in his vengeance while writing a scathing condemnation to Matilda. Yet his fury turns to devastating remorse when he discovers that Matilda was completely innocent—an unsuspecting victim manipulated by fraudulent letters and calculated falsehoods. Overwhelmed by the realization of his catastrophic mistake, St. Julian abandons his pride, committing the remainder of his broken life to solitude, misfortune, and quiet works of charity.

The People

• Count de St. Julian: A rigorous philosopher and devoted friend who strives to live by high moral principles. His rigid stoicism and absolute trust in his integrity are utterly shattered when betrayal drives him to commit a fatal act of vengeance, leaving him to spend his remaining days seeking redemption through charitable self-denial.
• Rinaldo, Marquis of Pescara: A wealthy, passionate young nobleman whose noble impulses are easily swayed by urban temptations and bad influences. Though initially eager to assist his friend, his weak disposition and unbridled romantic desires lead him to betray St. Julian by marrying Matilda, a decision that ultimately costs him his life.
• Matilda della Colonna: A gentle, highly principled woman of immense sensibility and modest fortune. She desires only tranquility, virtue, and filial duty, but she becomes the tragic pawn of manipulated letters and false reports, falling into involuntary guilt and profound grief.
• Marquis of San Severino: An elegant, highly articulate Neapolitan courtier whose smooth rhetoric and casual libertinism corrupt Rinaldo's youth, orchestrating much of the deceit that breaks the core relationships of the story.

In Its Own Voice

"Seduction, my dear lord, is an action that will yield in horror to no crime that ever sprang up in the degenerate breast."

— St. Julian fiercely scolds Rinaldo for contemplating the ruin of an innocent woman's virtue under the influence of Neapolitan flatterers.

"Many a friend could have promoted equally well the interests of the marquis of Pescara, but few lives are so valuable as thine."

— Matilda pleads with St. Julian prior to his departure, begging him not to risk his life across distant seas for an unnecessary legal errand.

"My lord, I shall not attempt to fly from the laws of my country. I am indeed the challenger, but I have done nothing, but upon the maturest deliberation, and I shall at all times be ready to answer my conduct."

— St. Julian addresses the onlookers with chilling calm immediately after running his former friend through the heart in their deadly duel.

What It's Really About

Beneath its sensational plot of intercepted letters and fatal duels, the book functions as an intense interrogation of Enlightenment philosophy, testing whether theoretical virtue can survive the pressure of human weakness. It asks whether strict moral rules, high-minded Stoicism, and intellectual pride can truly protect a person from the darker impulses of jealousy and vengeance. The narrative explores how easily open, unsuspecting minds are manipulated by malicious schemers, showing that innocence without suspicion is uniquely vulnerable to tragedy. Ultimately, the story argues that true moral greatness lies not in prideful judgment or honor-bound retribution, but in the painful work of self-examination, empathy, and active benevolence toward the suffering.

Why Read It Today

This epistolary novel offers readers a fascinating look into early romantic tragedy, delivering a psychological study of how high-minded ideals collapse under emotional stress. Modern readers will appreciate the sharp contrast between the characters' polished, elevated language and the raw, destructive passions driving their choices. The central dynamic—a mentor watching his star pupil slide into corruption, only to be consumed by his own righteous fury—feels remarkably modern in its psychological tension.

The primary difficulty for contemporary readers lies in its formal eighteenth-century prose. The characters write in long, highly stylized periods filled with elaborate declarations of virtue, formal etiquette, and philosophical musings that can slow the pace of the plot. Additionally, the extreme passivity of female reputation during the era and the rigid adherence to codes of honor may feel distant from modern sensibilities. Yet for those who enjoy psychological suspense, intense moral debate, and dramatic tragic arcs, this forgotten work stands out as an engaging narrative of misplaced trust and devastating remorse.
