The purpose of this article is to provide a unity to Heidegger's later reading of Parmenides. In the winter semester 1942-1943, Heidegger delivered a lecture course which was published posthumously under the title Parmenides as vol. 54 of Heidegger's collected works. Surprisingly, we find there actually very little on Parmenides himself. Therefore, in addition to considering the lecture course, I look for the Heideggerian interpretations of the Eleatic philosopher in An Introduction to Metaphysics, What Is Called Thinking?, "Moira," "Principle of Identity," "The End of Philosophy and the Task of Thinking," and "Seminar in Zahringen 1973." I organize my exposition of Heidegger's reading of Parmenides around Parmenidean fragments. I follow the traditional order of Diels-Kranz.
