"And did those feet in ancient time" is a short poem by William Blake from the preface to his epic Milton a Poem. The date on the title page of 1804 for Milton is probably when the plates were begun but the poem was printed c. 1808. Today it is best known as the hymn "Jerusalem," with music written by Sir Hubert Parry in 1916. The poem was inspired by the apocryphal story that a young Jesus, accompanied by his uncle Joseph of Arimathea, travelled to the area that is now England and visited Glastonbury. The legend is linked to an idea in the Book of Revelation (3:12 and 21:2) describing a Second Coming, wherein Jesus establishes a new Jerusalem. The Christian church in general, and the English Church in particular, used Jerusalem as a metaphor for Heaven, a place of universal love and peace. The poem implies that the visit of Jesus briefly created a heaven in England, in contrast to its post-industrial-revolution "dark Satanic Mills."
