Textual Complexity vs. Visual Simplicity

[Stefan Wirtz_2]

[..] on Panofsky's remark:

... it shows Jewish or Arab influence, probably in connection with the Kabbala; but also Dutch or Flemish influence in the female faces and figures and some Spanish or anyhow southern qualities. This last impression was strengthened in his mind by the character of the greens and red

In my language, this would be called "a steep thesis":
those dozens of yellow-haired / blonde women figures would allow the assumption of North / West Europeans, but not a special regional influence -- especially not by some red and green. 
And to bring in the Kabbala: oh boy.
