The following lists make no claim to absolute completeness, but no
genuine work by the painters mentioned, found in the better known public
or private collections, has been omitted. With the exception of three or
four pictures, which he knows only in the photographs, the author has
seen and carefully studied every picture indicated, and is alone
responsible for the attributions, although he is happy to acknowledge
his indebtedness to the writings of Signor Cavalcaselle, of the late
Giovanni Morelli, of Signor Gustavo Frizzoni, and of Dr. J. P. Richter.
For the convenience of students, lists of the sculptures, but the more
important only, have been appended to the lists of pictures by those
artists who have left sculptures as well as paintings.
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 doubtful. 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.
