In this eleven-volume complete transcription of the ‘Ambraser Heldenbuch,’ all texts appear in the original Early High German for the first time. A transcription that is faithful to individual characters used by the scribe is synoptically juxtaposed with the manuscript image. A second, diplomatic transcription is arranged by verses and numbered according to established editions. The lavishly illustrated manuscript of almost 250 parchment folios, commissioned by Emperor Maximilian I at the beginning of the sixteenth century, is one of the most important sources of German narrative literature of the Middle Ages. Volume 10 contains the two epics ‘Ortnit’ and ‘Wolfdietrich.’ The version of ‘Wolfdietrich’ in the ‘Ambraser Heldenbuch’ represents its own main version (A), which has not survived in any other manuscript.
