Butterfield is particularly well-known for her horse sculptures. Bronzes are cast from carefully selected branches, sticks, or metal objects, which cause the sculptures to resemble textured line drawings. Horse sculptures are placed in various locations around campus (Will Rogers, Masked Rider), but the Butterfield horse invites viewers to look at this animal in a new way. Works of art that encourage the viewer to study an animal, an object, or an idea from a fresh perspective seem particularly appropriate within a university, for the paradigm shift one experiences in an academic environment is often a gateway to intellectual growth and personal discovery.
