Mark di Suvero's monumental Iroquois has a robust energy and physical presence, which appeals to a wide audience. The abstract sculpture is formed from painted steel I-beams, which are emblematic of the artist’s use of industrial materials. A Chinese influence can be noted in the central knot shape and brilliant red color of the sculpture. Iroquois also has a characteristic kinetic element at its top. The open shapes invite public interaction and viewing from multiple angles. The artist has named seven sculptures for Native American Indian tribes: Mohican, Sioux, Shoshone, Miwok, Navajo, Catawba, and Iroquois.

Iroquois was acquired by the Fairmount Park Art Association in 2007 with support from David N. Pincus.
