Which of these best states the theme of this poem? from Eldorado
Gaily bedight,
A gallant knight,
In sunshine and in shadow,
Had journey long,
Singing a song,
In search of Eldorado
But he grew old,
This knight so bold,
And o'er his heart a shadow
Fell as he found
No spot of ground
That looked like Eldorado.
--by Edgar Allan Poe
