AND DID THOSE FEET IN ANCIENT TIME

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 those dark Satanic mills?

Bring me my Bow of burning gold:

Bring me my Arrows of desire:

Bring me my Spear: O clouds unfold!

Bring me my Chariot of fire.

I will not cease from Mental Fight,

Nor shall my Sword sleep in my hand

Till we have built Jerusalem

In England's green & pleasant Land.

William Blake

This is my favorite poem by William Blake to which Sir Charles Hubert Parry added music and retitled "Jerusalem".
