Pazzi-Verschwörung
For some time past he had been desirous of displaying his abilities and adding to his fame in Florence. 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. Lorenzo now invited him to profess Greek at Florence, and so Filelfo went there in 1481. Two weeks after his arrival he succumbed to dysentery, and was buried at the age of eighty-three in the Church of the Annunziata.
