A 1955 woodcut by M.C. Escher, featuring a geometric tessellation of fish that creates an illusion of depth through repeating patterns.

Depth, created by M.C. Escher in 1955, demonstrates the artist's preoccupation with tessellation and the mathematical division of a plane. This woodcut features a recurring motif of fish, arranged to fill the two-dimensional surface without leaving gaps. Escher employs a systematic approach to geometry, where the orientation of each figure shifts to accommodate the next, creating a sense of continuous motion across the paper. The visual structure relies on a repeating pattern that suggests a three-dimensional field despite the flat nature of the medium. The fish are rendered with precise, parallel lines that define their volume and texture. By varying the size and clarity of the figures, Escher creates an illusion of distance, where larger, more defined fish appear to occupy the foreground, while smaller, fainter versions recede into the background. This technique forces the eye to navigate the composition as if peering into a deep, aquatic space. Escher's technical precision is evident in the clean execution of the woodcut blocks. The limited colour palette, consisting of earthy tones and stark white, allows the viewer to focus on the geometric logic rather than decorative elements. The work reflects his interest in the interplay between positive and negative space, a theme that occupied much of his career. By transforming a simple biological form into a rigid geometric unit, he invites the viewer to consider the underlying order of the natural world. This print remains a clear example of his ability to merge artistic intuition with rigorous mathematical principles, resulting in a composition that is both orderly and visually engaging.
