Mikes Poppe
In a performance that lasted 438 hours, Mikes Poppe attached himself to a three-metre (10ft) chain buried in the middle of a block of marble in the courthouse of the Belgian coastal city of Ostend.
Poppe, who ate, slept, washed and drew while chained, worked to liberate himself by chiselling the away the stone towards the chain, but eventually had to be cut free.
"This block was symbolic of history, the history of art, which I am trying to free myself from. I discovered that this is not possible. It is burden which I must always carry," he said.
Entitled De Profundis, Poppe's performance was part of a larger exhibition and was live-streamed online.
With its roots in artistic experimentation a century ago and made famous by German artist Joseph Beuys in the 1970s, performance art combines visual art with drama.
Belgium's best known artist of the genre, Danny Devos, or DDV, has held over 170 performances around the world, including some depicting crime and murder.
Comment: Certainly a long performance, but art? If anything, Poppe demonstrates that self-imposed victimhood puts the self in a ridiculous situation. That was most probably not his intention, but the results are fairly ironic.
