the Fall of Gondolin is a tale written in 1916 - 1917 by J.R.R. Tolkien.

It is about its first text concerning the Ground of the medium. Written in a language voluntarily archaïsante, he reports the arrival of Tuor, guided by Voronwë, with Gondolin, the city with the seven names controlled by the king Turgon, the treason of the secrecy of the city by Meglin, the nephew of the king, the fall of the city in front of the armies of Morgoth after a baited resistance, and the escape of the rare survivors, carried out by Tuor and his wife Idril, the girl of the king.

In spring 1920, Tolkien lute this tale with the Club of Tests of the college of Exeter. It accepted warm welcome.

Tolkien wrote thereafter a shortened version of the tale, intended to be included in the Quenta Silmarillion (1938). In 1951, after having finished the drafting of the Lord of the Rings , it wrote a new version of the history the fall of Gondolin, which would be coherent with the remainder of the accounts of the First Age (those had undergone important modifications since 1917), but it did not finish this new version, stopping at the time when Tuor discovers the hidden city.

Christopher Tolkien published this last version, which it renamed De Tuor and of its arrival with Gondolin , in the unfinished Contes and legends . A few years later, it published the original tale of 1917 in the second Livre of the lost tales .
