Kane’s artwork visually follows Wagner’s musical fabric while retaining the means of expression characteristic of the comic-book format. His images do not autonomously narrate the tale; rather, they double the musical narrative form established by Wagner.
For example, the drama of Die Walküre begins not with the curtain opening on the first scene, but with its instrumental Vorspeil, which depicts the storm through which Siegmund is running. In his graphic version of the opera, Kane begins with four pages of pictures without text, depicting visually the action painted by Wagner’s orchestral score.
This according to “Od glazbene do slikovne drame: Roy Thomasov i Gil Kaneov strip Wagnerova Prstena Nibelunga by Zdravko Blažeković (Hrvatsko slovo: Tjednik za kulturu I/18 [25 August 1995] pp. 22–23).
