A brief extract from a poem "The fall of Gil-galad" -- sung Sam Gamgee to the company on Weathertop before the attack of the Nazgûl.

Gil-galad was an Elven-king.
Of him the harpers sadly sing:
the last whose realm was fair and free
between the Mountains and the Sea.

His sword was long, his lance was keen,
his shining helm afar was seen;
the countless stars of heaven's field
were mirrored in his silver shield.

But long ago he rode away,
and where he dwelleth none can say;
for into darkness fell his star
in Mordor where the shadows are.

"That's all I know," stammered Sam, blushing.
"I learned it from Mr. Bilbo when I was a lad."
