How did Analytical Cubism break from Renaissance ideas about perspective?

Analytical Cubism, developed by Georges Braque and Pablo Picasso, fundamentally rejected the Renaissance tradition of using linear perspective to create an illusion of depth on a flat surface.12

Instead of adhering to a single, fixed viewpoint, Analytical Cubism broke from these conventions in the following ways:

• Multiple Viewpoints: Rather than depicting an object from one angle, artists presented multiple, simultaneous views of a subject on the same canvas to convey more information than a single illusionistic view could provide.32
• Flattened Space: The movement emphasized the two-dimensional surface of the picture plane. By reducing objects to overlapping, opaque, and transparent planes, the compositions appeared to move forward toward the viewer rather than receding into a deep, illusory space.12
• Formal Analysis: Artists "dissected" forms, breaking them down into geometric facets and straight-line constructions. This process prioritized the structure of the object over its imitation, effectively refuting the idea that art should merely mimic nature.12
• Monochromatic Palette: By using a subdued, nearly monochromatic color scheme, the artists avoided distracting the viewer with color, focusing instead on the structural analysis of form and space.13
