The Heldenbuch (Book of Heroes) is a collection of Middle High German epic poetry from the second half of the 13th century, with some of the stories connected to the Nibelungenlied. The individual romances deal with the heroes of the Germanic tribes during the Migration Period: Ortnit, Hugdietrich and Wolfdietrich. King Ortnit of Lombardy falls madly in love with Sidrat, daughter of the heathen king Machorell of Muntebur. He gains the lady by abducting her from her father’s castle. The outraged Machorell sends two giant dragon eggs
to Ortnit’s kingdom and the lindworms that hatch cause misery and disaster throughout the country.
The 229 woodcuts, printed from 143 blocks (Kristeller 1888, no. 363), help tell the engaging stories. The iconography is based on earlier editions of the Heldenbuch. In addition to woodcut copies, here printed for the first time, Gran also used numerous woodblocks taken over from the Strasbourg workshops of Bartholomäus Kistler and Matthias Hupfuff.
