And Did Those Feet in Ancient Time (Jerusalem) by William Blake
Quick answer: Analysis of And Did Those Feet in Ancient Time, Blake's Jerusalem: its meaning, the dark Satanic Mills, its hymn afterlife, and lessons for poets today.
Blake buried this poem in the preface to his long prophetic work Milton, engraved around 1808, and it might have stayed obscure forever. Instead, set to music by Hubert Parry in 1916, it became the unofficial English anthem known simply as Jerusalem, sung at rugby matches, royal weddings and trade union meetings alike. Few poems have led such a strange double life: a private mystical vision turned public property.
The poem itself is stranger than its anthem status suggests. It opens with four questions about a legend Blake almost certainly did not believe literally, that the young Jesus once walked in England, and it ends with a personal vow of unending spiritual struggle. Reading it closely means recovering the fire under the familiar tune.
What the poem says
The first two quatrains are all questions. Did those feet, in ancient time, walk on England's mountains? Was the holy Lamb of God seen on its pleasant pastures? Did the divine countenance shine on the clouded hills, and was Jerusalem, the holy city, built here among these dark Satanic Mills? The honest answer to each is no, or at best, only in legend. Blake knows this. The questions are not historical enquiry; they are a way of asking whether the divine has ever touched, or could ever touch, ordinary English ground.
Then the poem pivots from asking to arming. The speaker calls for his bow of burning gold, his arrows of desire, his spear, his chariot of fire. The final stanza is a vow: he will not cease from mental fight, nor let his sword sleep in his hand, till Jerusalem is built in England's green and pleasant land. The movement is from doubtful past to willed future, and the hinge is the speaker's own decision to act.
How it works
Formally the poem is plain: four quatrains in rough iambic tetrameter, rhyming on the second and fourth lines. That plainness is strategic. Blake is writing something between a ballad and a hymn, a form ordinary people already knew how to carry, and Parry's tune later proved how singable it was. The fireworks are all in the imagery, which escalates from pastoral (mountains green, pleasant pastures) to industrial (the dark Satanic Mills) to apocalyptic (the chariot of fire, borrowed from Elijah).
The phrase dark Satanic Mills is the poem's most argued-over image. It evokes the new factories blackening the countryside of Blake's England, but readers have also taken it to mean the churches, the universities, or the grinding mechanical philosophy of the age. Blake likely wanted the blur. Notice also the phrase mental fight: the weapons are desire, imagination and unceasing effort, not literal steel. The sword that must not sleep is a poet's sword.
Why it lasts
The poem lasts because it holds two feelings almost every reader recognises: the suspicion that the world has gone wrong, and the refusal to accept that it must stay wrong. Its questions honour the doubt; its vow honours the refusal. That double movement lets radicals, patriots and dreamers of every stripe sing it and mean it, often meaning opposite things.
There is also the sheer afterlife. A visionary engraver who sold almost nothing in his lifetime wrote sixteen lines that a whole nation now knows by heart. For poets, that is a useful parable about the gap between recognition and worth, and about how a poem's music can carry its meaning into places its author never imagined.
What today's poet can steal
Steal the structure: questions first, vow second. A poem that spends half its length asking and half committing has a built-in emotional arc, and it avoids the preachiness of poems that are all vow. Try it with a civic subject, a place you love that has been damaged, and let the questions do your grieving before the resolve arrives.
Steal the strategic vagueness too. Blake's Mills work precisely because they name no single factory. One resonant, arguable image outlives a page of accurate complaint. Readers reward that arc from doubt to determination far more than they reward a static protest, because the movement itself is the feeling.
What poets can take from this
- Structure a poem as questions followed by a vow, and place the turn exactly halfway.
- Choose one symbolic image, like the dark Satanic Mills, and leave its referent deliberately open.
- Use a plain singable form when your content is visionary; the contrast keeps both alive.
- Borrow scriptural or mythic props (the chariot of fire) and put them in your own landscape.
- End on a future the speaker promises to build, not a present they merely lament.
Try it yourself
Write a sixteen-line poem about a place you love that industry, neglect or money has scarred. Spend the first eight lines on questions about what the place once was, and the last eight on what you vow to do.
Questions
What is the meaning of And Did Those Feet in Ancient Time?
The poem asks whether the divine ever visited England, invoking the legend that the young Jesus walked there, then vows to build Jerusalem, an ideal spiritual society, in England despite the dark Satanic Mills of the industrial age. It is a call to imaginative and moral struggle.
What are the dark Satanic Mills in Blake's Jerusalem?
Most readers take them as the factories of the early Industrial Revolution, but critics have also read them as established churches or the mechanistic thinking Blake opposed. The image is deliberately open, standing for whatever grinds the human spirit.
Is Jerusalem by Blake a hymn?
Blake wrote it as a preface poem to his epic Milton around 1808, not as a hymn. It became one in 1916 when Hubert Parry set it to music, and the song, titled Jerusalem, is now sung as an unofficial English anthem.
