The Abraham Poincheval 604,800 Seconds project features the French artist being sealed in a hole under the 'Histoire d'un Jour' bookstore in Marseilles, France for seven days.
Not having enough room to comfortably sit or stand, the artist filmed his experience as a way to explore the concept of claustrophobia. The only things Poincheval was able to do for the whole week's duration in that cramped space was to read books. When he finally came out from under his sealed tomb seven days later, the artist was quite shaky and unsteady, requiring a helping hand to keep him stable. He appeared to be experiencing a great deal of pain from moving his long-unused leg muscles in order to stand up.
The Abraham Poincheval 604,800 Seconds project is an experiment in discomfort.
