|Metal Engravings and Etchings
engraving and etching by hand, on copper or steel plates, were the methods used to
illustrate most bird books in the 18th and early 19th centuries, before the invention of
the more free-flowing techniques of lithography. After the plates were printed, typically
in black ink, color was added by hand.
Engraving is the art of incising lines, or designs, on a hard surface with a sharp
tool. The engraver must hold the engraving tool in one hand while moving the whole metal
plate with the other. Long shallow lines, rather than short sharp cuts, are easiest to
produce with this method. While a fairly stiff crisp image results, metal engraving allows
a freer line than wood engraving. To become a proficient engraver, an apprentice had to
serve some seven years. Etching, while similar to engraving, differs in that the plate is
incised by acid rather than by a cutting tool. The resulting image is usually light and
flowing, giving the impression of freehand drawing.
Etching was easier to learn than engraving, and most bird artists of the 18th century
learned to etch their own plates. It is sometimes difficult to tell by looking at a print
whether it was engraved or etched, and it is not uncommon to see etchings described as
engravings. In fact, a combination of the two methods was often used.
Some of the most famous bird artists of early America produced their illustrations
using metal engraving or etching techniques. This exhibition begins with a display of
works by three such artists Mark Catesby, Alexander Wilson and John James Audubon.
