First published in 1979, this is a genuine interdisciplinary work of nonfiction, with dozens of historical references and subtexts. Critics and reviewers have summed up its meaning in varying ways, yet consistently with praise. A mixture of art, philosophy, music, math, technology, and cognitive science, the book's title only reflects one aspect of its subject matter; namely, the connection between the work of mathematician Kurt Gödel, the artist M. C. Escher, and the composer J. S. Bach.
