If you're interested in medieval gold threads, there's a zoom talk at/from Yale University on Friday, April 2:

Department of the History of Art, Yale University, Medieval-Renaissance Forum: Gold on the Move. The Mongol Impact on 13th and 14th century Asian and Mediterranean Textiles.

It's at 12:00 pm Yale time, and if I did my time conversion correctly, that corresponds to 18:00 h German time. Which is a very reasonable time to listen to a talk!
