Reproductive Engraving

By Raphael Morghen's time reproductive engraving had become a highly specialized industry, utilizing myriad systems of web-like lines, dots, and lozenge shapes. This highly codified form of engraving is similar to that used to engrave paper money. At close range many forms appear to be clothed in an elegant fabric of lines, as if they were in a body stocking (you can see this clearly in the Virgin's neck, for example). The fabric on the Virgin's shoulder and the light grey background in the corners are also good examples of the subtleties of reproductive engraving.
