Rainer Maria Rilke Diskussionforum

Hello Forum,

Does anyone know of a publication which includes the letters of Rilke to princess Mechtilde Lichnowsky?

May thanks,

Julian

Maybe here: Jonas, Klaus W.: Rilke und Mechtilde Lichnowsky. – In: Modern Austrian Literature. Vol. 5, Nr. 1-2, (1972), S. 58-69.
But are there any other letters than the one of 1913-08-11, written in Heiligendamm?
