Abstract
The structural question how the six eye muscles with different insertions on the bulb and different tractive powers do co-operate with each other could not be solved by measurements. Therefore, listing gave an answer by mathematical topology (1845) and demonstrated it by a cardanic suspension. Helmholtz, Hering and others called the abstract hypothesis of listing later on a law. But this so called “law” does not cover all possible eye movements. Our model of a socket joint is a realistic alternative to listing. The consequences will be discussed.
