I just stumbled upon this painting by Reinhold Timm. It supposedly shows the musicians of Christian IV.
What's the instrument on the left? It looks like a Harp seen from a very weird angle... The painting is very interesting in general, it looks almost like some 1920s Neorealism. https://upload.wikimedia.org/wikipedia/commons/4/4e/Christian_IV%27s_musicians_by_Reinhold_Timm.jpg To get on or off this list see list information at http://www.cs.dartmouth.edu/~wbc/lute-admin/index.html
