EAGLE VISION OF 4 EZRA: Here's a web page by Kevin P. Edgecomb which presents various interpretations of the wings in the Eagle vision, along with his judgment of the most likely interpretation for each. He prefers DiTommaso's reading. There are other things on his website that look interesting, including additional pages on the Apocrypha and Pseudepigrapha and more (but I haven't had time to look at most of it).
