1. The innermost parts of a building, especially the sanctuary of a temple.
2. The most private or secret parts; recesses: the penetralia of the soul.
In this exhibition of new sculpture, her first in London since Perceval at the Serpentine Gallery in 2006, British artist Sarah Lucas exhibits a series of objects assembled from plaster casts of penises and flint. The variations on this formal starting point are like the haul of an archeological dig in the manner of a collection of Cycladic torsos or polytheistic relics, the repetition underlining its potency and timelessness, and the dynamism of the phallus as metaphor. The combination of the casts with flint references the presence of flint objects in the vaults and cabinets of archeological museums, mostly as examples of early weapons or fire-making tools, which marries with the potential power in an erection.
