          "He lives in a museum - alone - and likes
          it - keeps snakes as pets, is fanatically interested in primitive things,
          and does all his creative work at night,.. He doesn't make preliminary
          studies. He begins his pictures by completely finishing the head of
          the central figure; until this is rendered to his entire satisfaction
          he will not touch the work elsewhere." (E.W.Watson, Forty Illustrators and 
          How They Work ,op.cit. 1946).  
        His central theme, Riggs said, was "people and light".
