The tale of the creation of the Sun and the Moon, glossed “Song of the Sun and Moon” (S/99). Like the name Narsil, this name is probably a combination of the primitive roots √NAR and √THIL from which the words for the Sun and Moon were derived (Anar and Isil). The name is in the genitive plural (“of the”), but there is no element corresponding to “Song”, so a more accurate translation would simply be “Of the Sun and Moon”.
