Oromë's words in Elvish in the last panel here are quite possibly the earliest surviving Elvish sentence Tolkien ever wrote. It's not precisely how fully-developed Quenya from his later works would have worded it - that would be "Utúlieltë! Utúlieltë! Eldar utúlier!" - but it's recognisable. Presumably Oromë is speaking the original ur-language of the Elves of Cuiviénen here, rather than the Quenya dialect of those Elves who reached Valinor.
