"The idea of one form inside another form may owe some of its incipient beginnings to my interest at one stage when I discovered armour... an outside shell like the shell of a snail which is there to protect the more vulnerable forms inside."
- Henry Moore in conversation with David Mitchinson, 1980
"The helmet is a kind of protection thing, too, and it became a recording of things inside other things. The mystery of semiobscurity where one can only half distinguish something."
- Henry Moore quoted in 'Moore on his Methods', Christian Science Monitor, Boston, 1967
