Jerusalem

"Jerusalem" is an adaptation of Hubert Parry's hymn, with lyrics from "And did those feet in ancient time", a poem from the preface to William Blake's "Milton a Poem". Debuting on this track is the Moog Apollo, the first polyphonic synthesizer, still a prototype at the time.

"And did those feet in ancient time" is a short poem by William Blake from the preface to his epic Milton a Poem, 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 c. 1808. Today it is best known as the anthem "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, a tin merchant, travelled to what is now England and visited Glastonbury during the unknown years of Jesus. 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, has long used Jerusalem as a metaphor for Heaven, a place of universal love and peace.

In the most common interpretation of the poem, Blake implies that a visit by Jesus would briefly create 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. Thus the poem merely implies that there may, or may not, have been a divine visit, when there was briefly heaven in England.
