Hartmann von Aue's »Erec« is the first Arthurian romance in German and a central work of classical Middle High German literature. The present edition provides a thoroughly revised critical version of the text. The annex supplies a print version of the Middle High German »Erec« fragments discovered in 1978 and 2003, which independently of the familiar complete version relate back directly to Chrétien de Troyes' »Erec et Enide«.
