Earlier I sent a note saying that I was not able to locate a copies of
the Bosch paintings mentioned here:
According to Eliot (Poems, 1910-1930, p. 155), these details were
inspired by a painting from the school of Hieronymus Bosch (a
fifteenth-century Dutch artist), one called "Hell" or "The Sinful
World" and forming a diptych with Bosch's "Deluge." In a part of the
painting one can see a bat-like creature with dull human features
crawling headfirst down a rock wall.
I've tried another search and I believe that I have found these paintings.
My new method was to search out the paintings in Dutch.
