“As Tommy was sleeping, he had such a sight;
There thousands of sweepers, Dick, Joe, Ned, and Jack,
Were all of them locked up in coffins of black;

And by came an Angel, who had a bright key,
He opened the coffins and set them all free;
Then down a green vale, leaping, laughing they run,
And wash in a river, and shine like the sun.

Then, naked and white, all their bags left behind,
They rise up on pure clouds and sport in the wind:
And the Angel told Tom, if he’d be a good boy,
He’d have God for his father and never want joy.”

—William Blake, from The Chimney Sweeper.
