Ottger
Ottger, also known as Ottger von Wolfskeel, was a German knight and chronicler of the 13th century. He is best known for his work "Chronicon" or "Chronica", a chronicle of the Holy Roman Empire, which provides valuable insights into the political and social history of the period. Ottger's chronicle is particularly notable for its detailed accounts of the reigns of Emperor Frederick II and his son, Henry VII. It also includes descriptions of the Fourth Crusade and the subsequent sack of Constantinople in 1204. Ottger's work is considered one of the most important sources for understanding the medieval period, as it offers a contemporary perspective on the events and personalities of the time. Despite his historical significance, Ottger's life and background are not well-documented, and much about his personal history remains unknown. His chronicle, however, continues to be a valuable resource for historians studying the medieval era.
