French Artist Abraham Poincheval, who previously spent two weeks inside a bear sculpture, embarked on his latest feat, living inside a block of stone for a week. Poincheval will live in a body-shaped slot carved out from a limestone rock from February 22 to March 1, at Paris’ Palais De Tokyo contemporary art museum.

He will eat stewed fruit, soups and purees inside the stone block which is equipped with an air vent as well as personal items such as a log book. The artist is no stranger to living inside enclosed spaces. Poincheval spent 13 days living inside a hollowed-out bear sculpture in 2014, eating worms and beetles to mirror a bear’s diet.
