This is the first complete edition of the poetic correspondence between Rainer Maria Rilke (1875-1926) and the Viennese author Erika Mitterer (1906-2001). In addition to the poems exchanged by the two poets and prose letters by Mitterer, it includes texts by both authors associated with the correspondence and a diary account by Mitterer of their only meeting in November 2025. The edition of this previously underrated poetic correspondence draws on Rilke's unpublished notebooks and offers extensive previously unpublished material by Mitterer. A commentary and afterword help the reader to follow the complex interplay of voices and elucidate the unique significance of this correspondence as a dialogic work.
