An early depiction of one
An early depiction of one of these creatures with the epithet "golden" stood on a rhomboid limestone column atop a wooden base. A work that glorified Marie Bonaparte's sexual obsession is similar to depictions of these creatures, which were inspired by the works in the Maiasta series. One sculpture of these animals was taxed as a propeller blade when it was brought through U.S. customs. The sculptures of these creatures were stripped of detail to depict the essence of flight. For 10 points, name these animals that Constantine Brancusi sculpted "in space."
