The Moloch in "Howl" symbolizes a industrial machine
"Moloch whose mind is pure machinery!"
"Moloch whose skyscrapers stand in the long streets like endless Jehovahs! Moloch whose factories dream and croak in the fog! Moloch whose smoke-stacks and antennae crown the cities!"
"Moloch whose love is endless oil and stone! Moloch whose soul is electricity and banks! . . . Moloch whose fate is a cloud of sexless hydrogen!"
"Robot apartments! invisible suburbs! skeleton treasuries! blind capitals! demonic industries! spectral nations!"
