Albrecht von Bibra was one of the three patrons for the rebuilding of the church at Bibra in 1492. His coat of arms, along with Kilian and Lorenz’s, is above the altar. Also, I believe one of the three altars was commissioned by him. I believe he succeeded his cousin Kilian as head of the cathedral council, often the second most important position in the bishopric.
