Sára Tóth responds to Russell Perkin:
Yes, it is a possible explanation for my “surprise” that Frye read the Joseph story more realistically than usual. I cannot actually supply hard textual proofs that he also had in mind something similar to Luther’s allegorical-theological interpretation but that would certainly account for his reservations.
As to Thomas Mann, the notebook entry I quoted continues with a reference to him (which does not answer your question, though): “I’ve encountered several times the assertion that he’s a type of Christ; but what’s really Christlike about him? I’ve investigated Mann, but without result. The one thing that interests me is that he descends to Egypt and becomes, not the Pharaoh or temporal ruler, but his adviser, a Castiglione courtier. Castiglione’s book has always fascinated me… etc.”
