Summary

The ongoing technical study and conservation of an important 1513 hand-colored, printed edition of Ptolemy's Geographia at the Library of Congress has posed interesting challenges, especially in terms of the treatment of select maps that are in poor condition due to the presence of verdigris pigment on a poor quality paper, as well as a later restoration treatment. The speakers highlight the results of quantitative x-ray fluorescence (XRF) trace element analysis before, during, and after treatment of several maps, and discuss how this method of analysis has served as a key aid in the treatment decision-making process.
