From the Royal Academy of Art Magazine, the article “In Search of Wild Things”, written by Richard Cork:
"Epstein may first have decided to make this immensely daring tour de force while watching men and machines cutting stone in a quarry. He later recalled: ‘My ardour for machinery (short-lived) expended itself upon the purchase of an actual drill, second-hand, and upon this I made and mounted a machine-like robot, visored, menacing, and carrying within itself its progeny, protectively ensconced. Here is the armed, sinister figure of today and tomorrow.’"
