Federico Zeri

In 1984, when four students in Livorno hoaxed both the city and Modigliani experts into believing that a group of sculptures they have made were authentic, he was one of the few who called on their amateurish style.

[6] Zeri also argued that some of the frescoes in the Basilica of San Francesco d'Assisi, were made by Pietro Cavallini and not Giotto.

[1] Zeri's insistence that a painting can be attributed to an artist, by means of a careful examination or connoisseurship, without resort to external evidence such as documents or dates, met controversial responses.

[7] Zeri edited and researched catalogues of the collections of many institutions, including the Frederick Mason Perkins collection in the Sacro Convento in Assisi; Accademia Carrara; Museo Civico Amedeo Lia, La Spezia; Galleria Spada, Rome; The Metropolitan Museum of Art, New York; The Walters Art Museum, Baltimore.

[11] All through his life, Zeri maintained close connections with Bernard Berenson, Roberto Longhi, and his teacher Pietro Toesca.
