David Salle’s paintings juxtapose images from a variety of sources to startling and often provocative effect. In Sextant in Dogtown (1987) Salle arranges disparate elements within a grid and in a manner evoking film montage, while combing a pastiche of painterly styles and subjects. Here, the act of seeing — or not seeing– becomes a subject in itself. A half-dressed woman, lifted from the artist’s own photography, is shown from different vantage points, her face always obscured. Above her, a cartographer uses an old-fashioned measuring device known as a “sextant.” Confronted with these disjunctive images and with no evident narrative, we are ultimately left to forge connections on our own.
