Going to try to defend the name ‘Mt. Doom’.
(deep breath)
For starters, the word ‘doom’ has several meanings. The two important to this Tumbl are as follows:
1. Inevitable destruction or ruin.
AND
2. a judgment or decision
Tolkien tends to use both forms of ‘doom’ quite a bit.
“What shall we do with the Ring, the least of rings, the trifle that Sauron fancies? That is the doom that we must deem.” - Elrond
Now that we know that ‘doom’ can allude to a decision, we can relate that to Isildur’s decision to keep the ring after cutting it from Sauron’s hand at the end of the Second Age, AND Frodo’s decision to keep it rather than throw it into the fire at the end of LotR. So, we’ve got Mt. Doom: the mountain of ruinous choice, and Mt. Doom: the mountain of inevitable destruction… ‘cause it’s a big scary fuckin’ volcano in the heart of Mordor. Also, I always thought that Mt. Doom was kind of the layman’s term for it. Like, that’s what the men and hobbits called it. I know the elves called it Orodruin. It had a couple more names that I don’t remember.
It is a pretty funny picture, though.
