An alternative occult and esoteric history of England told through one of its most popular cultural forms: the comedy sitcom. Code: Damp is a sometimes-comedic field report that charts an esoteric code hidden within the twin poles of 1970s sitcoms Rising Damp and The Fall and Rise of Reginald Perrin. Outlining how past cultural patterns condensate and repeat through technology, time is shown to be a damp condensation seeping through the centuries and out onto the telly. Interspersed with the author’s own photographs, prints, Holsten Pils cans, local newspaper entries and carrier bags, as well as a whole host of other characters, the work seems an antiquarian’s conceit that takes time travel as a metaphoric methodology. This is not media studies; more an allegory of all reality as (tele)visual recorded history, excavating the strata of haunted technology from which the fragile band of code comprising our sense of time is briefly emitted. Drawing connections between incidents of ancient and popular culture, from Mark E. Smith’s lyric— “They say damp records the past”—to Rising Damp’s (meta)physical structure of decay, the book finds damp’s temporal power manifest in everything from alchemy, mysticism, and parish folklore to pulp, Time Team, darts, the local newspaper and, of course, the sitcom. Merging the vast with the parochial, the occult with the comedic, Code: Damp tunes into the weird demands of damp as a time-traveling material at the intersections of comedy, myth and technology, taking all three as serious resources to better (dis)orient the ground we stand on.
