In page Bruno of Querfurt:

"

Bruno was from a noble family of Querfurt (now in Saxony-Anhalt). He is rumoured to have been a relative of the Holy Roman Emperor Otto III.[citation needed] Through his mother Matilda, he was related to the future Bishop of Merseburg, Thietmar, with whom he studied at the cathedral school in Magdeburg, the seat of Adalbert of Magdeburg, the teacher and namesake of Adalbert of Prague.[1] While still a youth, he was made a canon of the Cathedral of Magdeburg. The fifteen-year-old Otto III made Bruno a part of his royal court. In 995, Otto III appointed Bruno as one of his court chaplains.[2]
