Bob Smith brought it to my attention that there is a recent thesis on “Joseph Smith, Mormonism and Enochic Traditions” by Salvatore Cirillo from Durham University. It is available online here:

I haven’t had a chance to read it yet, but it seems to critique Nibley and argue for JS authorship of the Book of Moses.
Update: I’ve read part and browsed a great deal. It is basically a critique of Nibley based on Quinn and Forsberg (without engaging their critics). It fails to engage any contemporary LDS scholarship on the topic. This is really unconscionable considering Nibley’s work is nearly 40 years old. The only part that I found of value was his less than 20 pages on ideas about Enoch in premodern and early modern Europe.
