'The igloo is the ideal organic form' according to Mario Merz, who equates it with the basic structures built by ancient nomadic cultures. This work addresses the theme of shelter and the relation of humans to their environment and community. Merz was part of the Arte Povera movement, which adopted a revolutionary stance against consumerist society, and deliberately made their work from humble materials. He began constructing igloos in 1968, in response to student and worker political demonstrations in Italy and France. The early igloos carried slogans linking them directly with the utopian ideals of the protesters.
