Squirrel 

This detailed watercolor painting of a squirrel by German artist Hans Hoffmann, dating back to 1578, is a prime example of 16th-century naturalism. The artist captures the animal’s anatomy and fur with astonishing precision, creating a lifelike image of the creature. The light brown tones of the squirrel's fur and the subtle nuances of its facial expression, coupled with its feathery tail, contribute to the painting's overall realism. This intricate depiction of a squirrel exemplifies the flourishing interest in scientific observation and detailed representation of nature during the Renaissance.
