'Horizontal Pyramides' by Alexander Calder is a lithograph from 1974, measuring 57 × 78 cm, and is hand-signed by the artist. A procession of sharp triangular forms — red, yellow, and blue — rises across a wide horizontal field, the tallest peaks breaking into an off-white sky while a broad black band anchors the lower register. The composition reads as a kind of geometric skyline, the triangles overlapping and clustering with the same rhythmic, balanced energy that defined Calder's approach to form in motion. Known primarily for his mobiles — a term coined by Marcel Duchamp — Calder brought the same sensitivity to weight, colour, and interval to his graphic work. This lithograph belongs to the body of flat, boldly coloured prints he produced in the 1970s, where primary colours and clean outlines stand in for the physical counterbalance of his sculpture.
