Where are Bablon, Ninwi, Towers Of Trui, and Rum?

[Vorondil]

On Page 111 of The Fall Of Gondolin it mentions Bablon, Ninwi, The Towers Of Trui, and Rum, and I wondered if these are mentioned anywhere else, and if so where are they located in Middle Earth?

These are mentioned also in Book of Lost Tales, Part Two... but without location.

It's said in the Appendix "The original test of Tuor A had Babylon, Nineveh, Troy, and (probably) Rome."
these were later changed to more "Middle-Earth" nomenclature.
I believe it refers to great battles and destructions, and the reference indicates the terrror Melko wrought on Amon Gwareth, among the Gnomes.

From the text in The Book of Lost Tales:
"Glory dwelt in that city of Gondolin of the Seven Names, and its ruin was the most dread of all the sacks of cities upon the face of Earth. Nor Bablon, nor Ninwi, nor the towers of Trui, nor all the many takings of Rûm that is greatest among Men, saw such terror as fell that day upon Amon Gwareth in the kindred of the Gnomes; and this is esteemed the worst work that Melko has yet thought of in the world." (Tolkien, J.R.R.. The Book Of Lost Tales, Part Two (History of Middle-Earth 2) (p. 196). HarperCollins. Kindle Edition.)

I'll continue looking... so far I don't think locations are given anywhere. Just references to great, dreadful events.

Addendum: No reference found in any of his other works, nor the Atlas of Middle-Earth, nor other resources about his works I have available electronically. There are 3 volumes of HoME not available electronically... I'll check those at some point. Outlook remains unchanged - additional references unlikely. (But there are Giants among us...and they may have more.)

If it's from BoLT 2, it would be the phase having Aelfwine as the supposed chronicler of the tales, at least 500 years later than Eriol, who is supposed to be roughly a contemporary of Hengist and Horsa in the 5th century.
From that perspective in time (10th century or somewhat later), Babylon, Nineveh, Troy, and ("western") Rome had long since fallen from their peaks of power. So their falls would be far in the past for Aelfwine. How much he as an Anglo-Saxon of that time could have known about them, apart from Rome, semms extremely dubious to me. Feels like an authorial intrusion by a much later writer poring over Aelfwine's writings; in real life, of course. it was JRRT himself.

I doubt that any mentions in later parts of HoMe can be found, as JRRT shifted the Ages of his legendarium back thousands of year. With the beginning of the Fourth Age shifted to about 4,000 BC (as per a letter), that would be 1,000 years before the first founding of Troy, whose existence almost perfectly parallels the duration of the Bronze Age (3,000-1,200 BC). All three other cities are far younger than Troy (or Ilion) I. If we assume the Red Book of Westmarch, the Thain's Book of Minas Tirith etc. playing a central role in the transmission of the legendarium, then the fall of the four mentioned cities lies thousands of years in the future ...
