London’s National Gallery has a new Boticelli. Well, not new exactly. The museum has reattributed a picture that had previously been attributed to one of the master’s followers. “The picture, ‘St Francis with Musical Angels’, is extremely unusual for a mid-15th century Florentine painting in its patterned, stamped gold background. The painting was purchased (as a Filippino Lippi) by the the National Gallery’s greatest director, Sir Charles Eastlake in 1858 from the Costabili collection.”
