During the 1970s, Bruce Nauman continued to expand his exploratory approach to art, engaging deeply with conceptual and physical aspects of the viewer's experience, language, and the artist's role in society. This period saw Nauman utilizing his own body as a communicative tool, further investigating the artist's authority and the delivery of wisdom to viewers. Notable works from this era include "Self Portrait as a Fountain," where Nauman humorously mimicked ornamental fountain nudes, satirizing the cliché of the artist as a prolific genius. "Green Light Corridor" (1970) is another seminal work from this period, highlighting Nauman's interest in viewer participation. This installation involved colored light, a recurring element in Nauman's oeuvre, inviting visitors to walk through it and thus complete the work through their experience. Similarly, "None Sing Neon Sign" (1970) and "Run from Fear, Fun from Rear" (1972) displayed Nauman's penchant for wordplay, incorporating language and communication through neon signs, showcasing his distinctive humor and engagement with linguistic structures. Additionally, "Raw War" (1971), a lithograph, and "Tony Sinking into the Floor, Face Up, and Face Down" (1973), a video work, underscored Nauman's ongoing fascination with language, perception, and the manipulation of the viewer's experience. The latter piece, involving an actor simulating sinking into the floor, played with physical and psychological dimensions of space and human vulnerability. Another significant work from this era, "Henry Moore Bound to Fail (Back View)" (1967-70), a cast iron sculpture, highlighted Nauman's critical engagement with the legacy and dominance of established artists like Henry Moore, using humor and wordplay to comment on artistic succession and originality. The 1970s were pivotal in Nauman's career, marked by a shift towards more interactive and experiential works that challenged traditional notions of art and spectatorship, while his continued use of neon, video, and performance further solidified his position as a key figure in contemporary art​ (UO Blogs)​​ (Encyclopedia Britannica)​.
