And did those feet in ancient time,
Walk upon England’s mountains green?
And was the holy Lamb of God
On England’s pleasant pastures seen?
And did the Countenance Divine
Shine forth upon our clouded hills?
And was Jerusalem builded here
Among these dark Satanic mills?

William Blake (1757-1827) English poet, mystic, artist
