...The map for Steinberg is not a system of geographic measurement but a way of thinking.... Maps also served Steinberg as autobiographical expedients: a street grid locating his New York apartment on 75th Street between Park and Lexington avenues; lying on a still-life table, a free-form map of Italy and Switzerland ending with “Überlingen,” the small town on Lake Constance where he regularly checked himself into a private clinic for physical recuperation. Among other cartographic inventions are maps charting emotional states or marked by angst-ridden road signs and rivers of aspiration.
