I don't believe this particular tome has been discussed previously, but I am genuinely intrigued to read noted Medievalist John M. Bowers' latest effort
Tolkien’s Lost Chaucer, in which Dr. Bowers uses Tolkien's notes from an abandoned project (a Clarendon edition of selected works of Chaucer), and intersperses additional biographical intersections of Tolkien and Chaucer.

I wonder if Chaucer's corrupted and wholly incorrigible Pardoner ever made his way into some of Tolkien's more vile characters.
