About the Lecture: 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.

An offline discussion on current approaches to verdigris treatment,
focusing on research shared at the ICOM-CC Graphic Document Working
Group Interim Meeting in Vienna, April 18-19, 2013 will follow the
lecture.
