A Small Rock at the Top of the Hill = A Big Rock at the Bottom of the Hill

Theo Wyatt Petrides
Survey of the negative potential energy of the fallen rocks on Agrigento’s ancient ruined city wall. Within the closed system of Petrides’ restoration choreography, the relative potential energy of one fallen rock is used to raise another rock, so conserving mass and potential energy. Each rock, in its journey back up the slope, finds itself following a complex snakes-and-ladders itinerary.
