This is a photograph of Elisabetta Gut's artwork, Book in A Cage, 1981, which I saw in Washington last year. I wish the photograph could adequately show how moving it was. The explanation read as follows:
"Book in a Cage represents humanity's struggle to communicate, set against the constraints it places on itself that prevent expression. The open door to the cage is a metaphor for the inherent liberty of ideas. The work, which places a French-Italian dictionary behind bars, also touches on the inadequacy of language to express thought and the isolation that can result."
