PRINCIPAL NORTH ITALIAN
Public galleries are mentioned first, then private collections, and churches last. The principal public gallery is always understood after the simple mention of a city or town. Thus, Paris means Paris, Louvre, London means London, National Gallery, etc.
An Interrogation point after the title of a picture indicates that its attribution to the given painter is not certain.
Distinctly early or late works are marked E or L.
It need scarcely be said that the attributions here given are not based on official catalogues, and are often at variance with them.
These lists are far from complete. The author hopes to revise them every few years, keeping them up to date with his further travels and researches.
