Soon after moving to Paris in 1926, Calder created his Cirque Calder. Made of wire and a spectrum of found materials, the Cirque was a work of performance art that gained Calder an introduction to the Parisian avant-garde. He continued to explore his invention of wire sculpture, whereby he “drew” with wire in three dimensions the portraits of friends, animals, circus themes, and personalities of the day.
