Between 1934 and 1942 Heidegger delivered three series of lectures on Hölderlin’s poetry. The discussion of “Der Ister” was the last of these, although Heidegger continued to think and write about Hölderlin into the 1960s. William McNeill and Julia Davis’s recent translation of the “Ister”— volume —is the first of the Hölderlin lectures to appear in English.
