One Year Performance 1978-1979 (Cage Piece) 

In this performance, which lasted from 29 September 1978 through 30 September 1979, Tehching Hsieh locked himself in an 11.5-by-9-by-8-foot (3.5 by 2.7 by 2.4 m) wooden cage, furnished only with a wash basin, lights, a pail, and a single bed.

 

During the year, he did not allow himself to talk, to read, to write, or to listen to radio and TV. A lawyer, Robert Projansky, notarized the entire process and made sure the artist never left the cage during that one year.

 

His loftmate came daily to deliver food, remove the artist's waste, and take a single photograph to document the project. In addition, this performance was open to be viewed once or twice a month from 11 am to 5 pm.
