Leviathan is a large rubbery structure, exhibited in Grand Palais by Anish Kapoor. Leviathan is also a sea monster referred to in the Bible. The word has become synonymous with any large sea monster or creature. In classical literature (such as the novel Moby-Dick) it refers to great whales, and in Modern Hebrew, it means simply “whale.” (wikipedia)
In Paris, Leviathan is so large that it almost touches the high glass roof of the Grand Palais. But that will only become apparent to you once you’ve escaped its innards. The entrance lead you inside the structure’s dark red belly. The sun, shining through the glass roof onto the top of the structure, is just bright enough to enable you to find your way to the exit and escape like Jonah from the whale’s belly. It’s only outside that you really see the enormous size of it, as it almost breaks out of its beaux-arts glass and steel cage.
