Orion
2007 .. H-53' X W-26'8" X D-20' [Painted Steel]

The artist draws inspiration from many sources including mathematics, physics, music, poetry and astronomy. The sculpture refers to the constellation named for the famed hunter of Greek mythology.

Johnny Appleseed.
1989-93 ... H-23' X W-22' X D-44' [Steel and Stainless Steel]
Mark di Suvero is recognized by contemporary art scholars and critics for inventing a radical style of art which challenges the very nature and defiunition of sculpture. Built from steel and found materials such as wooden beams and scrap metal, this abstract assemblages are large in scale and powerfully expressive. Open forms that unfolds and thrust outwards, his sculpture define and describe the space they occupy.

A bent steel I-beam rests high overhead on a bearing that enables it to move in the wind. the five-ton element appears weightless as it spins and rocks gently up and down.

An excerpt from the stand ... "Mark di Suvero does not make technical drawings or models from his large scale work. He engages directly with the material making the sculptures himself. He draws free hand onto steel plates which he considers his paper and the arcs he cuts out with a cutting torch express the compass reach of his outstreatched arms. Using a crane he brings steel plates and beams together welding and bolting them into place. He would also cold bend the steel with an anchor and a crane, a technique that can be seen in Rust Angel, Shang and Yoga."
These sculptures are on display ...
