Dear Friend Heckel,
I hereby give to you, for so long as you are in the unhappy position of a President of the Grand-ducal Theatre-committee at Mannheim, the right to perform every portion of my "Ring des Nibelungen" as often as you like and for nothing.
To the Mannheim theatre, which stands on a certain list of mine, I will not bate a farthing.
This is the full earnest
of your
old friend
Richard Wagner.
