The Marriage of Heaven and Hell "A Memorable Fancy" plate 14 (1790 - 1793). Inspired the title of Aldous Huxley's 1954 book about drug experimentation, The Doors of Perception, which in turn inspired the name of the 1960s rock group The Doors.
Attributed to Ludwig van Beethoven by Bettina von Arnim in a letter to Goethe (May 28, 1810), as quoted in Bettina von Arnim "Goethe's Correspondence with a Child", 1835.
