This is the twenty-seventh follow-up entry to the post, “Gagarin and the Seven Heavens”.
The previous posts ranged across a number of authors at different times and places and religious affiliations, and were not organized well into any outline, so I ordered them; further, the follow-up posts were becoming so numerous, and the text block listing and briefly introducing them was so large, that they were soon going to take up more space than the posts themselves. Thus, I organized and listed them here.
