"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".
