Josep Llorens i Artigas (Barcelona, 1892–1980) was a renowned Catalan ceramist and art critic, considered one of the central figures in the renewal of 20th-century artistic ceramics. Initially a member of the Noucentista group Courbet, he established himself as an art critic before moving to Paris in the 1920s to dedicate himself entirely to ceramics. His work is characterized by a deep knowledge of glazing and firing techniques, with pure forms and refined textures. His international fame is inextricably linked to his long and fruitful collaboration with the artist Joan Miró, which began in the 1940s. Together they created monumental ceramic murals, including the famous "Wall of the Sun" and "Wall of the Moon" for the UNESCO headquarters in Paris (1958), as well as works for Harvard University and the Barcelona airport. Thanks to his technical mastery, which made it possible to translate Miró's pictorial language into the ceramic medium, Artigas received important recognition, elevating ceramics from a craft to an autonomous art form.
