Until now, there has been no complete critical textual edition of the works of Günther, after Carl Enders was unable to realize his publishing plans and since Wilhelm Krämer’s edition remained incomplete. The new edition takes all of the works of the great Silesian poet into consideration, including their preliminary stages and fragments. The commentary section provides detailed explanations of the textual legacy and dissemination, including musical settings of the poetry and translations. The occasions and dates for writing the poems are discussed, and difficult sections are explained. Thus, literary critics and friends of literature will at last have a secure foundation for interpreting the texts.
