The Victorian period was not only a haunted age; it was also, in every sense of the word, a hallucinatory age, lending itself to every type of illusion, even at the level of bricks and mortar. The Victorian house, the Victorian street, encouraged illusion and hallucination, the Victorian theatre was a hotbed of optical tricks, only the kitchen escaped the obsession with the manufacture of articles which appeared to be something else: moneyboxes disguised as books, substantial-looking doors that on examination was merely cunning paintwork, solid-looking chairs that were, in fact, featherlight, being manufactured from papier mache.
