This dazzling Cubo-Futurist painting shows a knife-grinder, blade in hand, bent over his sharpening stone. The artist achieved a hall of mirrors quality by showing repeating, successive layers of interlocking planes. The mechanistic hands, with green and yellow fingers, repeat as the figure moves; the feet, in black shoes and bent legs also replicate outward. It’s as if we can see a series of consecutive viewpoints and moments in time simultaneously. Cubo-Futurism combined the abstract geometry of Cubism with the fragmented forms of Futurism. In this painting, you can see the style’s characteristic breaking down of forms, alteration of contours, and intersection of spatial planes.
