Thomas Bewick, an English naturalist and woodcut engraver working during the 18th and 19th centuries, was by all accounts at the top of his field during his lifetime. He combined tools originally developed for metal engraving and innovative techniques that introduced the gray scale into what was previously a black-and-white medium with tremendous wit and artistic talent. In doing so, he created engravings that still delight audiences today. His devotion to the natural world (birds in particular) as well as his interest in fairy tales led to the creation of images so intricate and detailed that they often had to be examined with a magnifying glass in order for the full effect to be realized. Here’s an overview of some of his most noteworthy engravings.
