The artwork, titled “Convex and Concave,” was created by M.C. Escher in 1955. It belongs to the Surrealism art movement and is categorized under the genre of capriccio.
“Convex and Concave” exemplifies Escher’s mastery of intricate geometric illusions and spatial distortions. The artwork depicts an impossible architectural structure with interconnected, cascading stairways that lead to nowhere, arches that blend into one another, and figures situated in paradoxical positions. The composition creates a continuous cycle of upward and downward directions, challenging the viewer’s perception of reality. In black-and-white tones, the artwork encapsulates Escher’s fascination with the concept of infinity and the boundaries of visual perception.
