Representative of the artist's vision, this work, installed in 1988 in the Michelet district, features undefined lines, varying according to viewpoint and offering no reference points in space. It explores the concept of contrast between the work and its context: its visual force lies in the examination of geographical and arithmetical representations that transform the atmosphere of this public space. The 12-metre-high monumental sculpture is part of a series of works whose (non)logic inspired the name Doubles lignes indéterminées.

Born in 1941 in the Alpes de Haute-Provence region of France, Bernar Venet began painting at an early age. He first came to prominence working with tar, which he spread on canvases in the early 60s. Wishing to redefine the boundaries of art, he was at the forefront of conceptual art, which is why he moved to New York in 1966. His art increasingly drew on the world of mathematics and pure science. After a hiatus devoted to writing and teaching, in 1983 he asserted himself in the field of sculpture, creating the steel lines that would make him world-famous. For the past twenty years, his work has been displayed in parks, gardens, museums and exhibitions the world over.
