Galadriel’s mirror

[tifo_gcs]

I think that's reading a bit too much into it, though one can never be sure with Tolkien's constant tinkering around with manuscripts.
What I think is worth noticing is that the Mirror can be made every time Galadriel pours more water into the basin. In that way, Galadriel's magic cannot be lost, unless Galadriel herself is lost, and there was a long and complicated thread about the (im)mortality of elves previously (as you should know). Point being, the mirror won't just be lost.
Earendil the evening star is remade in Galadriel's phial, and the star itself reappears every night. But the star is one of Feanor's actual silmarils. Here Galadriel mirrors Feanor's feat of capturing light. And I don't see the phial as being very transitory.

The point I'm trying to make is that I see too many inconsistencies for there to be any significance, but it could be interesting if someone could convince me of the opposite. But this is straying off topic
