Sun (Middle-earth)

The sun of Middle-earth was created by Aule; he and his people made a vessel to hold the radience of the last fruit of Laurelin. The vessel of the sun was guided by Arien, a Maia.

"...and Anar the Fire-golden, fruit of Laurelin, they named the Sun. But the Noldor named [it] Vasa, the Heart of Fire, that awakens and consumes; for the Sun was set as a sign for the awakening of Men and the waning of the Elves..."
