Burchard of Worms (c.950 - August 20 1025) was the Roman Catholic bishop of Worms in the Holy Roman Empire, and author of a Canon law collection in twenty books, the "Collectarium canonum" or "Decretum". Wikipedia
He rebuilt the walls of Worms and with the approval of Henry II tore down the stronghold of a certain Duke Otto, which served as a place of refuge to criminals and malefactors. www.newadvent.org/cathen/03064a.htm
The life was composed, it seems, soon after Burchard's death in 1025 by a canon of Worms, perhaps Ebbo/Eberhard, cathedral master and custodian of Worms and later bishop of Konstanz (1034-46). www.fordham.edu/halsall/source/1025burchard-vita.html
