From a MetMuseum.org online release:
This exhibition traces the first sixty years of the etched print (circa 1490 to circa 1560), from its emergence in the workshop of the German printmaker and armor decorator Daniel Hopfer to the years when a range of artists from Germany, Flanders, Italy, and France began experimenting with etching. Approximately 125 etchings, produced by both renowned and lesser-known artists, are displayed alongside a number of drawings, printing plates, illustrated books, and armor.
The history of printmaking has been punctuated by moments of great invention that have completely changed the course of the medium. The beginning of etching in Europe in the late fifteenth and early sixteenth centuries—when the technique moved out of the workshop of armor decorators and into those of printmakers and painters—represents one of those pivotal moments. Etching, essentially drawing on the surface of a metal plate, had an ease that opened the door for all kinds of artists to make prints. The pioneers of the medium included some of the greatest painters of the Renaissance, such as Albrecht Dürer, Parmigianino, and Pieter Bruegel the Elder.
