In our first moments of life, instinctively, we need to breathe and perform the biological function of “being in the world.” Thus, from very early on, breath has been associated with the soul or spirit that gives life to the body. This prepared the way for cosmic and religious visions of life. And although breath as a vital element has always been represented in art, it is mainly since Marcel Duchamp that the phenomenon of breathing has been used in art works to experiment with various sensory experiences. This issue brings together articles that consider various ways of depicting breathing, particularly those associated with current conditions of breathing in an environment where the air often is deemed unhealthy.
