The fact that Georg Trakl's poetry frequently contains allusions to Hölderlin, Rimbaud, the Bible, and to various additional authors is well known. The presence of Büchner's Lenz and of some other texts in Traum und Umnachtung has, however, not yet been recognized. Some twenty-two specific passages from Lenz, adapted and modified in various ways, occur in the second section of Traum und Umnachtung. In addition, Trakl paraphrases texts by Nietzsche in the first section and cites Hölderlin in the third; the last section comprises most of the major themes from Trakl's own work. The concentration of allusions to a specific author in single sections of Traum und Umnachtung suggests that Trakl's use of citations is conscious. Such a recognition does not involve an “intentional fallacy”: the author's intention, in incorporating allusions and quotations into his work, is comparable to his intention in choosing a certain kind of form. Both citations and forms can be identified with the proper training: a work of literature containing conscious allusions (Zitatendichtung)must be treated as a literary form in its own right, in which even simple, apparently descriptive phrases no longer refer to objects or experiences, but to the tradition of poetic language.
