The opening of the Louvre-Lens has been an exceptional opportunity to rethink the centuries-old relationship between the collections in the Louvre Museum and its visitors. This publication presents the outstanding instances in this innovative project, made possible by the creation, over a former pithead, of a new architectural complex by the Japanese firm SANAA and its internationally renowned architects Kazuyo Sejima and Ryue Nishizawa. At the heart of this museum is the "Galerie du Temps", whose design was entrusted to Studio Adrien Gardère. It presents 230 exhibits from all the departments in the Louvre in a single space. Displayed in chronological order, these works have previously always been seen in separate exhibition spaces, being issued from different civilisations, schools or techniques. The "Galerie du Temps" offers a comparative and transversal view of the history of the arts, spanning the period from the invention of writing in Mesopotamia in the 4th millennium BC to the Industrial Revolution in the mid-19th century. On this journey through different civilisations, the gallery allows visitors to compare universally recognised masterpieces, such as Gudea, Prince of Lagash, the statue of The Majordomo Keki, the Discophoros, the Angel's Head mosaic from the basilica in Torcello, the Portrait of Doña Isabel de Requesens, Vice Queen of Naples, formerly known as the Portrait of Jeanne d'Aragon, by Raphael, the Bather by Falconet, the Allegory of France before the Return of General Napoleon Bonaparte from Egypt by Jean-Pierre Franque. This guide to the Louvre-Lens discusses and reproduces in their entirety the works exhibited in the "Galerie du Temps", allowing us to prolong and deepen our visual encounter with art and history.
