Turambar and the Foalókë

Turambar and the Foalókë is the second chapter of The Book of Lost Tales 2, which is the second volume of The History of Middle-earth. It tells of the earliest version of the tale of Turin Turambar and his encounter with Glaurung. This early version had been written by Tolkien sometime around 1919.

The chapter that follows is "The Fall of Gondolin".

Chapter synopsis
The story of Túrin and the dragon Glorund is told by one named Eltas, as requested by Lindo. The story he narrates remains very accurate to its later and final version in Quenta SiImarillion, and its drawn-out version in The Children of Húrin, save for numerous namings that would later be altered: Following Eltas' telling of this tale, Christopher Tolkien gives his notes and analyses of things such as the manuscript and typescript versions of the story, the changes underwent of character names, plot, events, and of things referenced in other early, various Middle-earth tales Tolkien had written, along with comparisons of said things.
 * Túrin is initially only named "Turambar". In the final version of the story, Turambar is an epithet given to him later.
 * Throughout not only this tale but all tales compiled into The Book of Lost Tales 2, "Gnome" is the term referring to the race of Arda that later would be emended to "Elf". Thus Gnomish was the term that referred to the language later named Sindarin.
 * Foalókë, in the setting wherein Eltas tells this story, is a term that translated as "name of a serpent that guarded a treasure", from the Quenya words foa ('hoard' or 'treasure') and lókë ('snake'). The name refers to the dragon Glorund, who, like the familiar and later Smaug of The Hobbit, claimed and guarded a hoard of valuable jewels, deep within Nargothrond.
 * Aryador was the name of the land of Hisilómë among Men. Hisilómë was later changed to Hithlum.
 * Mormakil, one of the epithets given to Túrin (meaning 'black sword'), would later be changed to Mormegil.
 * Failivrin was the name of the female Gnome who later would be changed to Finduilas.
 * Galweg is the earlier name of Failivrin's father, whose name would later be changed to Orodreth.
 * Nínin-Udathriol was the first Gnomish (i.e. Elvish) name given to the Battle of Unnumbered Tears. In the final version of this tale, the battle is called Nirnaeth Arnoediad.
 * Flinding is the name of the character whose role would later be mostly taken over by Gwindor, an elf of Nargothrond.
 * Gurtholfin was the first name given to Túrin's sword. The name meant 'wand of death', and was later changed to Gurthang, which means 'death of iron'.
 * Peleg was the name of the father of Tuor. This name would later be changed to Huor.
 * The Great Wrack is the term Eltas uses to refer to the end of the world, whereat Túrin would "stand beside Fionwë" while Melkor curses Tuúrin's sword.
