Saint George Crivelli's
Underdrawing Tricking the Eye
with Pastiglia Painting with
Tempera Silver and Gold
Before beginning his restoration, chief conservator Gianfranco Pocobene studied the painting in detail. This analysis revealed insights into Crivelli's techniques and helped him to prepare for the treatment. One technique, infrared reflectography (IRR), allows us to see traces of Crivelli's preparatory drawing beneath the paint.
