~ Vom Gral ward ich zu euch daher gesandt ~
This is a porcelain stein with lithophane and a transfer scene of the Swan Knight Lohengrin. The verse is from the third act of Richard Wagner's opera "Lowengrin".
Vom Gral ward ich zu euch daher gesandt mein Vater Parzival trägt seine Krone sein Ritter ich-bin Lohengrin genannt.	I was sent to you by the Grail: my father Parzival wears its crown, I its knight - am called Lohengrin..
