On 26 April 1478, during Easter Mass in the Florentine Cathedral of Saint Mary of the Flower, a group of conspirators, led by Jacopo and Francesco de' Pazzi, attacked Lorenzo and his brother Giuliano in what would become known as the Pazzi conspiracy. Francesco Nori shielded Lorenzo during the first assault, dying stabbed in his place by the hand of Bernardo Bandini. His gesture allowed Lorenzo to realize the danger and to escape his other aggressors, Stefano da Bagnone and Antonio Maffei, determining the failure of the conspiracy and the definitive rise of Lorenzo to Lord of Florence.[1][2]
Before the conspiracy, Francesco had commissioned the sculptor Antonio Rossellino to create a marble sculpture of the Nursing Madonna. This was used by the Nori family to create a Mausoleum for Francesco in the Santa Croce Church, facing Michelangelo’s tomb. Lorenzo never honored Nori’s death. [1][2][3]
