The Encounter with Marco Lombardo

On the Third Terrace of Mount Purgatory, where the sin of Wrath is purged in a dense, acrid smoke that blinds the penitent, Dante and Virgil encounter Marco Lombardo. A nobleman from the Veneto who lived in the thirteenth century, Marco is a soul of sharp intellect and worldly experience, and his encounter with the pilgrim becomes the occasion for one of the poem's most sustained and explicit treatments of free will, moral responsibility, and the corruption of earthly authority. His words cut through the fog of the terrace to address the root causes of the world's disorder, making this meeting a pivotal moment in the Purgatorio's education of Dante.

The Setting and the Voice in the Smoke

The encounter takes place within a "smoke" so thick that it deprives the sight entirely, a fitting punishment for the wrathful, whose anger clouded their reason in life. Dante, blinded, must proceed by touch and sound, clinging to Virgil's shoulder "as a blind man goes behind his guide, lest he should wander, or should strike against aught that may harm." From within this bitter and foul air, voices are heard singing the "Agnus Dei" in perfect harmony, a prayer for peace that contrasts sharply with the discord of anger. One voice, however, singles out Dante, addressing him directly and asking how he, still living, can be present and speaking of time as if he measured it by the calendar. This voice belongs to Marco, who, upon learning that Dante is a living man journeying through the afterlife by divine grace, agrees to guide him toward the correct path upward.

Marco Lombardo: Identity and Worldly Wisdom

Marco identifies himself as a Lombard who "knew the world" and loved that excellence at which "each one now has unbent his bow." This phrase captures his lament for a lost age of virtue and courtesy, a theme that resonates throughout the Purgatorio. He was a courtier and a man of affairs, familiar with the politics and moral decay of his time. His punishment on the Terrace of Wrath suggests that his own anger, perhaps a righteous indignation at the world's corruption, was itself a sin that required purgation. Yet his discourse is not the bitter rant of a damned soul but the measured, sorrowful analysis of a penitent who has come to understand the deeper causes of the evil he once fought against.

The Discourse on Free Will and the Causes of Evil

Dante, troubled by Marco's assertion that the world is "utterly deserted by every virtue" and filled with iniquity, asks him to explain the cause. He notes that some attribute everything to the influence of the heavens, while others place the cause on earth. Marco's response is a masterful defense of human free will. He argues that if all actions were necessitated by the stars, then free will would be destroyed, and there would be no justice in rewarding good or punishing evil. The heavens, he says, initiate movements but do not compel; humans are given "light" and "free volition," which, though it may struggle at first against celestial influences, can conquer all if properly nurtured. The true cause of the world's depravity, Marco insists, is not a corrupt nature but "evil guidance." He traces this to the fatal confusion of the two powers that should govern human life: the spiritual authority of the Church and the temporal authority of the Empire. Rome, he declares, once had "two suns" that illuminated the two roads—the road of God and the road of the world—but one has quenched the other. The sword has been joined to the crozier, and this unnatural union has led to the corruption of both. The Church, which should be concerned with spiritual matters, has meddled in temporal affairs, and the Empire, which should provide justice and order, has been neglected. This diagnosis is a direct and powerful critique of the political and ecclesiastical situation of Dante's own time, particularly the interference of Pope Boniface VIII in secular governance.

The Lament for a Lost Age and the Prophecy of Decline

Marco's discourse is not merely abstract; it is grounded in a specific historical and geographical lament. He recalls the region between the Po and the Adige, where "valour and courtesy used to be found, before that Frederick had his controversy." This refers to the conflict between Emperor Frederick II and the papacy, which Marco sees as the beginning of the moral collapse of Italy. Now, he says, anyone can pass through that land without shame, for the good are shunned. Only three old men remain as a reproach to the present age: Currado da Palazzo, the good Gherardo, and Guido da Castel, whom he calls "the simple Lombard." These figures represent a vanishing ideal of nobility and virtue. When Dante asks who this Gherardo is, Marco expresses surprise that a Tuscan does not know him, and identifies him only by his daughter Gaia. This exchange underscores the depth of the moral amnesia that has overtaken the world. Marco's final words are a warning: the Church of Rome, by "confounding in itself two governments, falls in the mire, and soils itself and its burden." This is the core of his teaching: the root of all evil is the usurpation of temporal power by spiritual authority, a theme that will echo throughout the Paradiso.

The Departure and Thematic Significance

As Marco finishes his discourse, he notes that the dawn is breaking through the smoke, signaling the approach of the Angel who guards the passage to the next terrace. He must depart, and he does so with a blessing, leaving Dante and Virgil to continue their ascent. The encounter with Marco Lombardo is a crucial moment in the Purgatorio's exploration of moral philosophy. It provides a clear, reasoned, and passionate argument for human free will and moral responsibility, countering any deterministic or fatalistic interpretation of the universe. It also offers a devastating critique of the political and ecclesiastical corruption of Dante's era, laying the blame not on the stars but on the choices of men, especially those in power. Marco's voice, emerging from the smoke of wrath, is a voice of clarity and conviction, a call to recognize the true sources of evil and to take up the burden of reform. His teaching prepares Dante for the higher truths he will encounter in the Earthly Paradise and the celestial spheres, where the proper order of love and authority is finally revealed.
