But the Louvre-Lens’ masterstroke is a collection in one place which represents all the civilisations of the world, from the emergence of script (3,500 BC) to the middle of the 19th century. La Galerie du Temps is a 120m long agora, home to 200 masterpieces (paintings, sculptures, mosaics, bas-relief, sarcophagus) from 8 sections of the Paris Louvre. Every year on the anniversary date 4th December, 20% of the collection is renewed. For example, Liberty Leading the People by Delacroix was replaced by Oedipus and the Sphinx by Ingres. For a year now, 20 new works are housed there including treasures like Poussin’s Grand Bacchanale, and Belisarius Begging for Alms by David.
