Leonor de Cisneros watched her husband burn alive rather than recant. She recanted, and lived. Nine years later, she would choose the death she had once refused.
Around 1551, Carlos de Seso, an Italian nobleman living in Spain, founded a secret Protestant congregation in Valladolid. Within a few years it had grown to roughly seventy members, meeting undetected under the noses of a court and clergy that would have burned every one of them for what they believed. Antonio Herrezuelo and his wife, Leonor de Cisneros, joined in 1554.
The congregation survived four more years on secrecy alone. In 1558, an Edict of Faith prompted two separate denunciations, and one member, a servant named Cristóbal de Padilla, was arrested. Padilla managed to send a warning out of his cell to Herrezuelo, who passed it on to another member of the group. The alarm spread through the congregation in whispers. Some fled. Some turned themselves in and denounced others outright, hoping confession would buy them mercy. On Maundy Thursday, 23 March 1559, the authorities raided the house where the group was meeting and arrested most of those still inside, Herrezuelo and Leonor among them.
They were brought to trial together. Herrezuelo refused every opportunity to recant. Leonor, facing the same stake, did not.
On Trinity Sunday, 21 May 1559, the Inquisition staged its auto de fe in the Plaza Mayor of Valladolid before the regent, Juana, and her thirteen-year-old nephew, Prince Carlos. Fourteen condemned heretics went to the stake that morning. Thirteen were strangled first, the customary mercy for those who had confessed. Herrezuelo was not. He alone among the fourteen was burned alive, his jaw held shut by an iron gag through which he had been unable to speak since his arrest.
Leonor stood among the reconciled, dressed in the sanbenito of a penitent rather than the mark of the unrepentant. As the guards led Herrezuelo past her toward the fire, the gag held his mouth closed, the same gag that had silenced him through every hearing since March. He turned his head as far as the procession allowed and looked at her. Nothing else passed between them. He was moved on toward the flames.
Leonor's sentence was three years' imprisonment in a Benedictine monastery, along with the confiscation of everything she owned. At some point within those three years, she began speaking again of the faith she had renounced, to the other prisoners around her, inside the one institution built specifically to listen for exactly that.
The Inquisition spent years trying to bring her back to recantation the way it had once already. The attempts failed, one after another, for years, before the tribunal gave up and moved to try her instead as an incorrigible relapsed heretic, a category with no path back to mercy. One contemporary account, describing her once it was clear nothing would move her, called her "this stubborn woman," whose obstinacy nothing could shake.
Under Inquisition procedure, a relapsed heretic received no second confession and no strangulation before the flames. Leonor de Cisneros was burned alive in Valladolid on 26 September 1568. She was thirty-two.
