I had a question posed about this situation late last year, but it was never answered.
So, the answer is the sun (Anar) and moon (Isil) illuminate the Ilumen. Anar and Isil. From the words we get Minas Anor (later, Minas Tirith) and Isildur (devoted to the moon). His name implys his kinship with the elves.
The Maiar who were related to the sun and moon were Arien (Anar) and Tilion (Isil)???
Ok, now I'm going to have to subscribe to the thread, since I'm bound to not check back...
