This was cobbled together by Knight's brother, G. Wilson Knight (the Shakespeare scholar), from notes left after the author's death. Elysion isn't exactly groundbreaking (not even for 1970!), but its one (minor) virtue is that it was written by a spiritualist nut who confesses midway through to "astral journeys" in his sleep. If only there were more of that and fewer unimaginative readings of Virgil.
