Rock on Top of Another Rock is a sculpture by the artists Peter Fischli and David Weiss which was exhibited outside the Serpentine Gallery in Kensington Gardens in 2013.
It consists of one large rock balanced on top of another large rock. An earlier incarnation of the work was a similar sculpture on the plateau of Valdresflya which was one of the artworks installed on each of Norway’s eighteen scenic highways.
The motto of Fischli and Weiss is “Am schönsten ist das Gleichgewicht, kurz bevor’s zusammenbricht” — balance is most beautiful just at the point when it is about to collapse. Fischli spoke about the work at its unveiling in March 2013:
In Norway and here, to put one rock on top of another rock in the wilderness is the first thing you do if you want to make a mark. When you walk and you want to find your way back…you make this mark. It is a very archaic, simple thing, but it is referencing the Venturi duck. We wanted to make something that forces you to stop your car and get out to take a photograph.
Radic liked the work and commented, “A Fischli and Weiss rock is different from a Smiljan Radic rock. We are thinking about the same objects in a different way. How we put it in a space is really different. [Although] in the end, it’s a rock”.
