From etchings scratched into the earliest monuments, to the spray can designs that appear on structures today, the urge to leave our mark is universal. But in 18th-century Britain, the nature of graffiti changed; both exploding in popularity and becoming much more radical in nature. Speaking to Elinor Evans about her new book, Writing on the Wall, Madeleine Pelling explores this shift. She investigates the stories behind scraps of graffiti, from chalk markings made by soldiers and sex workers, to glyphs scratched onto windows by famed poets, and reveals what they can tell us about life in 18th-century Britain.

(AD) Madeleine Pelling is the author of Writing on the Wall: Graffiti, Rebellion and the Making of 18th-century Britain (Profile).
