Maman the spider. A work created in 1999 by the avant-garde artist Louise Bourgeois (1911-2010). The personally motivated work of the artist, known primarily for her sculptures, fits perfectly with the monumentality of the Guggenheim Museum. With the personally motivated work, he pays tribute to his mother, who was a weaver. It simultaneously suggests protector and predator, strength and fragility, devotion and fear. His enormous height of almost 9 meters and the wobbliness of his slender legs convey a poignant vulnerability. A fascinating sight. Enhances the impact of the museum and its environment.
