Wagner's choice of subjects had from the outset shown an imagination far above that of any earlier librettist; yet he had begun with stories which could attract ordinary minds, as he dismally realized when the libretto of Der fliegende Hollander so pleased the Parisian wire-pullers that it was promptly set to music by one of their friends.
