It's amazing how many things can resemble genitalia when viewed in the right context, and since the early 1990s Sarah Lucas has explored this phenomenon with gusto. "NUD NOB" features a host of biomorphic abstractions, contorted figures, phallic fruits and straight-up sculptures of penises. Lucas has previously produced similar works in soft materials like stockings and cast-off clothing. Here, most of the sculptures are cast in bronze and polished to a mirrored finish. Whether seen as a display of ludicrously expensive juvenile humor or penetrating psychoanalytic imagery, "NUD NOB" delivers a Freudian bite.
