The Seven Lamps of Architecture is an extended essay by John Ruskin, an English art critic and theorist, published in 1849. This article refers to a specific unexpurgated copy of the book with paranormal properties, one which was published in 1845, a year before Ruskin supposedly began writing it.
The book gives a sense of walls pressing in around the reader, and may physically entomb them. It interacts differently with Robert Smirke's architecture. Reading it while in a building designed by Smirke allows the reader to control their surroundings.
