I am doing my doctoral studies at the University of Bonn in Germany. Upon visiting the Landes Museum today, I came across two paintings that might be of interest to you, both featuring the same title, “Anbetung der Könige” (Adoration of the Magi). I have attached photos, with details, to this message.
PS, your blog is wonderful. I am an art historian myself, specialized in medieval Egypt, and I find your posts ever insightful.
