Overall a nice concept and good post. On the Corn-Dolly, it reminds me of the straw figure that is used to put a curse on someone (according to Chinese superstition). . Alternatively, I think there're also dolls which ppl made in ancient China that were supposed to summon a spirit who could then do household chores for the family. However, I think I like the innocent 'vulnerable' Corn-Dolly much much better than either of the two real-life folk traditions I mentioned.
I remembered running into this Codex the first time 2 years ago and thinking "Wow". Strangely, despite this and numerous subsequent run-ins with this through individual submissions, somehow I never voted on the Codex itself. Correcting this now.
