Boldogs, Gothmogs and Sauron's New Clothes

[Petty Dwarf]

Two things leading up to this thread: I was reading through the orc material in Myths Transformed and the discussion on the Ring's part in Sauron's several re-embodiments that was taking place in Rings of Power & Osanwe-Kenta.

It becomes a huge problem to assert validity with the texts, especially for some of the short working notes in Myths Transformed. My preference is to defer to the most recent and more polished parts whether internal or external to the story. So this from the Orcs section of Quendi and Eldar carries lots of weight

For Morgoth had many servants, the oldest and most potent of whom were immortal, belonging indeed in their beginning to the Maiar; and these evil spirits like their Master could take on visible forms. Those whose business it was to direct the Orcs often took Orkish shapes, though they were greater and more terrible. Thus it was that the histories speak of Great Orcs or Orc-captains who were not slain, and who reappeared in battle through years far longer than the span of the lives of Men.*

*Boldog, for instance, is a name that occurs many times in the tales of the War. But it is possible that Boldog was not a personal name, and either a title, or else the name of a kind of creature: the Orc-formed Maiar, only less formidable than the Balrogs.

Christopher goes on to mention the only times the name Boldog was used was in the Lay of Leithian and Quenta as the name for an orc-captain who lead a raid into Doriath. Fair enough. Maybe Tolkien intended to write him in at later times, put Quendi and Eldar aside and forgot.

But I have a feeling he meant for Boldog to be applied in the latter sense: as a class-name for Orkish Úmaiar. It seems clear from the piece above that being killed is hardly an end for certain Úmaiar, and in doing so it diminishes them. So considering this, are there any possible Boldog candidates out there? There aren't many. One name from older legends seems to intrude into later ones: Gothmog. Could a Balrog become a Boldog?

There is no textual evidence the second Gothmog was the same as the first, or that he was a Boldog, or that he was an orc, or a Ring-wraith either. So the floor is open to suggestions.

It seems if there were any Úmaiar powerful enough to rehouse themselves Balrogs would have been able to do it. Of course it would take very long, much longer than Sauron took to rehouse himself, but he had the Ring. That makes his case special. I doubt Sauron would have died the same death as Thû had the revision of the Lay of Leithian continued. It's more than likely that the first time Sauron died was in the Downfall.
