This is a summary of the methods which a restorer may use to distinguish later additions. These are grouped in 4 sections: (1) historical and iconographical criteria, (2) differences visible in ordinary light to the naked eye, or under low magnification, (3) differences revealed by special equipment, (4) differences revealed by cleaning. Such a summary, however complete, can do no more than aid a restorer, who relies much more on his skill and experience than on the nature of the methods he uses. (G.T.)
