Agostino Bonalumi
Agostino Bonalumi (Italy, 1935–2013) was a key figure in post-war Italian art, known for his 'extroflexed' canvases that push painting into three dimensions. Associated with the Spatialist movement, his innovative works combined geometric precision with dynamic forms, redefining the boundaries between painting and sculpture.

What is abstract art?
Abstract art uses form, shape, line, and color to create a visual experience without attempting to represent external reality. The composition exists independently of the world's visual references, focusing on expressing ideas and emotions through non-representational means.
