Le Grand Verre de terre is an artist book that accompanies the special anniversary issue of Matador magazine. It collects the impressive images that the Mallorcan artist made for the National Library of France, in Paris in 2016: a gigantic fresco of 190 meters long by 6 meters high made in clay on the crystals of the mythical library and populated by the fantastic shapes, animals and creatures that shape Barceló's imagination. A living work, conceived to be observed from inside and outside the building, which introduced the visitor to an extraordinary exhibition. The fresco was erased by the artist when the exhibition ended, and only the memory of these pages remain.
