>>7403146>>7403184>>7403364generally, a symbol depicted upside-down represents the antithesis of the original symbol's meaning/dogma
hence the upside down pentagram, and the cross (I'm sure theres others, and more elaborate changes made when the symbol is vertically symmetrical, like the medicine wheel)
The story (one of them) goes, with saint peter, that he didn't feel that he was worthy to be crucified in the same manner as christ, and requested to be done upside down.
>romans probably said alrigh dude whatever, your literal funeralnot entirely sure how christian theology regards/interperets the right side down cross, but its probably not how regular dickheads see it and think "oh no call a priest! the demons are in my jigglebelly doll!"
