The Art of Observation and the Observation of Art: Zadig in the Twenty-first Century.

Astute observation is a fundamental component of the art of medicine. Yet most schools and residencies offer little formal teaching of this skill, with some outsourcing the entire subject matter to art museums and instructors. Curiously, it was nineteenth century medicine that may have provided the conceptual framework for what is now known as Visual Thinking Strategy, the technique used by many art-based programs in order to teach observation. We suggest that the time is ripe for medicine to regain ownership of the teaching of this skill, not only because it may enhance clinical care but also because only the eyes of a skilled physician can best interpret crucial medical details. To this end, we shall revisit both the method of Zadig, which William Osler practiced and taught to his students, and its application to the observation of art first pioneered by the Italian physician Giovanni Morelli. As an example of this skill, we shall use focused observation to decode a fifteenth century portrait that hangs at the Philadelphia Museum of Art, thus turning a seemingly non-descript Renaissance painting into a treasure trove of personal, social, and medical information.
