"And did those feet in ancient time" is a poem by William Blake from the preface to his epic Milton: A Poem in Two Books, one of a collection of writings known as the Prophetic Books. The date of 1804 on the title page is probably when the plates were begun, but the poem was printed . Today it is best known as the hymn "Jerusalem", with music written by Sir Hubert Parry in 1916. The famous orchestration was written by Sir Edward Elgar. It is not to be confused with another poem, much longer and larger in scope and also by Blake, called Jerusalem The Emanation of the Giant Albion. It is often assumed that the poem was inspired by the apocryphal story that a young Jesus, accompanied by Joseph of Arimathea, a tin merchant, travelled to what is now England and visited Glastonbury during his unknown years. Most scholars reject the historical authenticity of this story out of hand, and according to British folklore scholar A. W. Smith, "there was little reason to believe that an oral tradition concerning a visit made by Jesus to Britain existed before the early part of the twentieth century". Blake does not name the walker on "Englands green and pleasant land"; according to a story available at the time of Blake's writing, in Milton's History of Britain, Joseph of Arimathea, alone, travelled after the death of Jesus, and first preached to the ancient Britons. The poem's theme is linked to the Book of Revelation (3:12 and 21:2) describing a Second Coming, wherein Jesus establishes a New Jerusalem. Churches in general, and the Church of England in particular, have long used Jerusalem as a metaphor for Heaven, a place of universal love and peace. In the most common interpretation of the poem, Blake asks whether a visit by Jesus briefly created heaven in England, in contrast to the "dark Satanic Mills" of the Industrial Revolution. Blake's poem asks four questions rather than asserting the historical truth of Christ's visit. The second verse is interpreted as an exhortation to create an ideal society in England, whether or not there was a divine visit. Text The original text is found in the preface Blake wrote for inclusion with Milton, a Poem, following the lines beginning "The Stolen and Perverted Writings of Homer & Ovid: of Plato & Cicero, which all Men ought to contemn: ..."
