Sauron's name

[gondowe]

I don't like so much to speculate things not written by the professor, we have what we have as a mythology. In this case we have to note that both Melkor/Morgoth and Mairon/Sauron had turn to evil long ago (in the case of Sauron is speculative) the Elves awake. So we can say what we want, for example that the other Valar describe both as mighty and admirable before their fall. But Melko(r) did exist as a developed character in the original conception and Sauron as Sauron (not Tevildo or Thû) was developed as character in TLOTR. So Tolkien had to create a "past" for him.

But, as I said before, is speculate in a mythology as it stands, being from the point of view of the Elves (earlier), or mannish (later).
