Intended as a tribute to her mother, who was a weaver, Bourgeois's spiders are highly contradictory as emblems of maternity: they suggest both protector and predator—the silk of a spider is used both to construct cocoons and to bind prey—and embody both strength and fragility. Such ambiguities are powerfully figured in the mammoth Maman, which hovers ominously on legs like Gothic arches that act at once as a cage and as a protective lair to a sac full of eggs perilously attached to her undercarriage. The spider provokes awe and fear, yet her massive height, improbably balanced on slender legs, conveys an almost poignant vulnerability.
