"He [Celeborn]
has dwelt in the West since the days of dawn, and I have dwelt with him years uncounted [starting in Doriath];
for ere the fall of Nargothrond or Gondolin [generally speaking, especially as some of the listeners are Hobbits: "a long long time ago"]
I passed over the mountains [Ered Wethrin, then on to Doriath]
and together through ages of the world we have fought the long defeat."
