Text: In Richard Serra’s “One Ton Prop” four lead plates each 250 Kilos are propping each other up. Gravity itself is the structural principle. The existence of sculpture here relies on an unstable balance, not the illusion of balance, like what you get in a composition, but actual balance. There is a coincidence between the “representing” and the “represented” element. This idea was once a quality that was natural to Architecture. Herzog and De Mouran explored this in some of their earlier work, particularly in some of their warehouses- see Ricola Warehouse in Laufan.
