Fig. 1From: Visualizing and measuring gold leaf in fourteenth- and fifteenth-century Italian gold ground paintings using scanning macro X-ray fluorescence spectroscopy: a new tool for advancing art historical researchRepresentative schematic drawing showing the application of four gold leaves in a (a, b) regular grid pattern typical of large gilded areas and c, d irregular grid application pattern typical of those found along curved edges of panel or haloed figures. Note that for the purposes of comparison, the four equilateral sides of any individual leaf (top, bottom, left, and right) are designated by the overall orientation of the object. Vertical and horizontal leaf length measurements are shown in yellow arrows; vertical and horizontal leaf overlaps are shown in black arrowsBack to article page
