The Heldenbuch, or "Book of Heroes," is a collection of German epic poetry that focuses on heroic tales, particularly those of the Nibelungenlied and other legendary figures. During the Baroque period, several poets and scholars showed interest in this work and its themes. Here are a few notable figures:

1. Martin Opitz (1597-1639): A prominent poet and theorist of the Baroque period, Opitz is known for his contributions to German literature and his efforts to elevate the German language in poetry. He was influenced by earlier epic traditions, including the Heldenbuch.

2. Paul Fleming (1609-1640): A poet who was part of the Baroque literary movement, Fleming's work often reflected themes of heroism and the human condition, resonating with the narratives found in the Heldenbuch.

3. Andreas Gryphius (1616-1664): A significant figure in Baroque literature, Gryphius wrote tragedies and poems that often drew on classical and medieval themes, including heroism and moral dilemmas, akin to those in the Heldenbuch.

4. Daniel Caspar von Lohenstein (1635-1683): A playwright and poet, Lohenstein's works often incorporated heroic themes and were influenced by earlier epic traditions, including the Heldenbuch.

5. Johann Christian Günther (1695-1723): Although slightly later than the traditional Baroque period, Günther's poetry reflects the influence of earlier epic traditions, including the Heldenbuch, and he is known for his exploration of heroic and tragic themes.

These poets and scholars contributed to the Baroque literary landscape by engaging with themes of heroism, morality, and the human experience, often drawing inspiration from earlier works like the Heldenbuch. Their interest helped to keep the narratives and themes of these epic tales alive in the cultural consciousness of their time.
