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.

 – J. R. R. Tolkien

Gil-galad means “Star of Radiance”; he is also named Ereinion, “Son of Kings”, Artanáro, “High Flame” in Quenya, which is Rodnor in Sindarin.
