A portrait of Joanna of Castile by Juan de Flandes, ca. 1500.
As seen through the letters of Peter Martyr d’Anghiera. - Peter Martyr d’Anghiera (1457–1526) was an Italian humanist, scholar, and letter-writer who lived at the heart of the Spanish court during the reign of the Catholic Monarchs. Born in Lombardy and trained in Renaissance humanism, he came to Spain in the late 15th century, where he became tutor to princes, royal chronicler, and trusted observer of events that would change the world. His extensive correspondence (Epistolae) offers a rare, vivid view of court life, politics, exploration, and personal drama—written not as official history, but as thoughtful, often candid letters to friends across Europe.
When Philip the Handsome died suddenly in September 1506, Joanna of Castile was just twenty-seven years old. She was a young queen, newly widowed, already isolated, and the mother of several small children. Her eldest son, Charles—only six years old at the time—would one day become Emperor Charles V, but now he was a frightened child watching his mother collapse into grief. What followed shocked courts across Europe. In his Epistolae, the humanist Peter Martyr d’Anghiera describes not a legend of madness, but a human tragedy unfolding in public view.
A Grief That Would Not End
Peter Martyr was close enough to the Spanish court to witness events as they happened, and careful enough to record what he saw without turning it into rumor. In his letters, Joanna’s grief is not theatrical—it is consuming. She does not behave as a queen should. She does not follow the rituals expected of widows of rank. Instead, she clings to her dead husband with a devotion that unsettles everyone around her.
Philip’s body is embalmed, but Joanna refuses to let him be buried. Martyr writes that she keeps the coffin close, watches over it, and resists all pressure to part from it. This is not a symbolic delay. Days stretch into weeks, weeks into months. The court waits. Europe watches.
Traveling with the Dead
What most disturbed contemporaries—and what Martyr records with quiet astonishment—was Joanna’s decision to travel with Philip’s coffin. She orders the casket opened repeatedly, needing to see his face, to reassure herself that he is truly there. At night, she insists that no women be allowed near him, as if jealousy still bound her to the man she had lost.
The cortege moves slowly through Castile. Towns receive a queen accompanied by death. Priests whisper. Courtiers exchange glances. Martyr does not sensationalize the scene, but the strangeness is unmistakable. This is mourning without limits, grief that refuses containment.
A Court Without Patience
Peter Martyr’s letters make clear that sympathy quickly gave way to fear. Joanna’s behavior was not only emotionally troubling—it was politically dangerous. She was the rightful queen of Castile, yet increasingly incapable of fulfilling her role. Decisions were delayed. Authority slipped away from her hands.
Her father, Ferdinand of Aragon, watched closely. So did advisers, nobles, and foreign powers. In Martyr’s words, concern for Joanna’s soul slowly merged with concern for the stability of the realm. Compassion became calculation.
Madness or Despair?
What makes Martyr’s testimony so valuable is what he does not say. He does not call Joanna mad. He does not mock her, nor dismiss her as hysterical. Instead, his letters reveal a man deeply uncomfortable with what he is witnessing. He describes sorrow pushed beyond endurance, love turned inward, reason overwhelmed—but never erased.
Modern readers often forget how little space early-modern society allowed for uncontrolled grief, especially in women, and especially in queens. Joanna’s refusal to move on violated not only custom, but political necessity. Martyr seems to understand this tension, even as he struggles to name it.
Silence After the Coffin
Eventually, Philip is buried—against Joanna’s will. Not long after, she is declared unfit to rule. Her son Charles is separated from her and raised to govern an empire. Joanna herself will spend the next nearly fifty years confined in Tordesillas, alive but absent from power, a queen in name only.
Peter Martyr’s letters stop short of that long imprisonment, but they capture the moment when everything turns. In his Epistolae, Joanna of Castile is not yet “la Loca.” She is a young widow, devastated by loss, standing at the point where private grief becomes a public sentence.
A Human Voice in a Brutal Time
Through Peter Martyr’s eyes, Joanna’s story regains its humanity. His letters remind us that behind the labels of history—madness, incapacity, confinement—there was a woman who loved deeply and lost catastrophically. Her grief frightened a world that valued order over compassion, stability over empathy.
In that sense, Joanna’s tragedy is not only personal. It is a story about how power responds to vulnerability—and how history often mistakes sorrow for madness when it becomes inconvenient.
