Years had healed the breach between him and the Medici family; and on the occasion of the Pazzi conspiracy against the life of Lorenzo de' Medici, he had sent violent letters of abuse to his papal patron Sixtus, denouncing his participation in a plot so dangerous to the security of Italy.

Two weeks after his arrival he succumbed to dysentery, and was buried at the age of eighty-three in the Church of the Annunziata.
