No Jardim do Amor, estava escrito na porta da Capela, "Tu não podes". E ainda ataram com nó espinhoso os desejos e gozos do poeta.

The Garden of Love

I went to the Garden of Love,
And saw what I never had seen:
A Chapel was built in the midst,
Where I used to play on the green.
And the gates of this Chapel were shut,
And "Thou shalt not" writ over the door;
So I turned to the Garden of Love,
That so many sweet flowers bore;
And I saw it was filled with graves,
And tombstones where flowers should be;
And Priests in black gowns were walking their rounds,
And binding with briers my joys and desires.

William Blake
(1757-1827)
