““Codes proved their value many times over in wartime. Far less obvious, though, is the way hidden messages found a place in another setting with universal significance. Here the intent was not to deceive an enemy but to intensify a sense of mystery, not to achieve military conquest but to produce greater appreciation. It is in art and in some of its most famous expressions that we readily realize an important truth: artistic geniuses often produced their greatest works when they incorporated concealed meanings in their masterpieces.””
