Renaissance engravings are objects of exquisite beauty and incomparable intricacy that are composed entirely of lines. Artists began using this intaglio process in Europe as early as 1430. This captivating catalogue focuses on the height of the medium, from 1480 to 1650, when engravers made dramatic and rapid visual changes to engraving technique as they responded to the demands of reproducing artworks in other media. The Brilliant Line follows these visual transformations and offers new insight into the special inventiveness and technical virtuosity of Renaissance and Baroque (Early Modern) engravers. The three essays discuss how engraving’s restrictive materials and the physical process of engraving informed its visual language; the context for the spread of particular engraving styles throughout Europe; and the interests, knowledge, and skills that Renaissance viewers applied when viewing and comparing engravings by style or school.
