About the structure, there are two main stanzas. Blake was a romantic poet, so, in this poem the language is common, and the structure is linear.
The First stanza is a question, and the second is the answer, as the ‘’The Lamb’’; the two stanzas are consequential, and they are two octaves.
The First stanza:
In this stanza we have 4 questions at the past, and there are a correspondence of grammatical structure.
In fact, this stanza in specular because in the first and in the third couplet we have the past with ‘’Did’’, in the second and in the fourth couplet we have the past ‘’was’’, so we can say that this is a technically perfect structure;
The Second stanza:
This octave is the consequence and the answer of the first stanza. This stanza is divided in two parts:
In the second we have the future, so, it is a promise: he will not cease his battle until the construction of a New Jerusalem on British hills.
About the content, in the first stanza we have the past because he is nostalgic of the beauty that there was in England before the industrialization; In fact he defines factories as satanic mils: these mils that have brutalized the English landscape. Also, in the first couplet he tells us about those feet, and in the second couplet we have the confirmation that those feet are of Jesus Christ, because he is symbolized by the holy lamb.
In the second stanza we have a request of metaphorical weapons, as the chariot of fire, because, his promise in the second part is that he will not cease his mental battle.
So, he requires metaphorical weapons because he fight a mental battle, and his sword is his pencil: he will not cease to send his message to the people, the common people, until he has built Jerusalem in England’s green and pleasant land.
So, we have we have a strong presence of pantheism, the spirituality that lies in earthly things.
