Thinker on a Rock is a bronze sculpture by Barry Flanagan.
Brian Ferriso, executive director of the Philbrook Museum of Art, said:"The playful subject matter clearly references several art historical traditions, including that of Rodin. In addition to the subject, this work's expressive nature encapsulates the artist's unique ability to create three-dimensional 'gestural' drawings with bronze."There are eight casts of the work, with six of them installed at:
