At the Philadelphia Museum of Art until April 6, an exhibition of tapestries by the major South African artist, William Kentridge. The Porter tapestries “stem from a series of drawings in which he conjured shadowy figures from ripped construction paper and collaged them onto the web-like background of nineteenth-century atlas maps.” The Philadelphia Inquirer has more; the reviewer explores why they were done as tapestries, with the final products woven from mohair by weavers at the Stephens Tapestry Studio. A book is also available.
