Heldenbücher (singular Heldenbuch "book of heroes") is the conventional title under which a group of German manuscripts and prints of the 15th and 16th centuries has come down to us. Each Heldenbuch contains a collection of primarily epic poetry, typically including material from the Theodoric cycle, and the cycle of Hugdietrich, Wolfdietrich and Ortnit. The Heldenbuch texts are thus based on medieval German literature, but adapted to the tastes of the Renaissance.
