Buonamico Buffalmacco

Buonamico di Martino or Buonamico Buffalmacco (active c. 1315–1336) was an Italian painter who worked in Florence, Bologna and Pisa. No recorded work of his survives, although he may be the Master of the Triumph of Death, the painter of a fresco cycle in the Camposanto in Pisa.  

Boccaccio (in his Decameron) and Sacchetti (in his Il trecentonovelle) both describe Buonamico as being a practical joker. Giorgio Vasari includes a biography of Buonamico in his Lives.
