In the early 1820s, in the gloomy aftermath of the 1789 Revolution and the Napoleonic wars, the French Romantic painter Theodore Gericault (1791-1824) made five portraits of patients in an asylum or clinic. No depictions of madness before or since can compare with them for humanity, straightforwardness and immediacy. Why were they painted? For whom? Art-historical ways of accounting for them open up questions about the nature of psychoanalytic interpretation. The portraits challenge us to find responses in ourselves to the face and the embodied mysteries of the other person, and to our own internal (unsconscious, disavowed) otherness: in this sense, Gericault was a painter-analyst . The challenge could not be more urgent, in our world of suspicion of the stranger, and of the medicalisation of madness. The book sketches the history of this last process, from the Enlightenment through to the Revolution and its public health policies, to the birth of the asylum in its interface with the penal system.
