A modern woman in erotic repose. A pair of dancing satyrs. A black 17th-century coach. An avenging angel from the Renaissance. Such are the subjects taken up by the New York artist Rachel Feinstein in her recent exhibition at Marianne Boesky Gallery, Apr. 24-May 23, 2008. Feinsteinís manifold themes are matched by her embrace of a range of sensuous materials: finished wood, copper, cement, polyester, resin.
