1478. On April 26, in the Cathedral of Santa Maria del Fiore in Florence, the most dramatic episode of the Renaissance was staged: Bernardo Bandini, Francesco Pazzi and Antonio Maffei attacked Giuliano and Lorenzo de' Medici. The first dies, the second is injured. However, the crowd takes the side of the Magnificent and the conspiracy will end in a bloodbath and will result in a bitter conflict between the Italian states.
The story is told by Giovanni da Montesecco, the man of the "great refusal": charged with murdering the brothers, he shirks the task a few hours before the massacre.
His confession takes us directly into the heart of that era and sheds light on the thorniest issues of the Pazzi Conspiracy.
