As one of the largest frescos in the Arcadian Retreat series, Catastrophe is extremely heavy. When the work is installed at SFMOMA, six art handlers and a forklift or hydraulic lift are needed to move it from its crate to the wall. To protect and stabilize the plaster, each panel is mounted on an aluminum backing board. These supports are reinforced by additional metal cross-braces. In this view, the piece is secured to a metal cart for inspection. When the work is viewed from the front, its complex metal structure is nearly invisible; the three panels appear to float within their wooden frame.
