Analysis of Eldorado

Gaily bedight,
                   A gallant knight,
               In sunshine and in shadow,
                   Had journeyed 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.

And, as his strength
                   Failed him at length,
               He met a pilgrim shadow-
                   "Shadow," said he,
                   "Where can it be-
               This land of Eldorado?"

"Over the Mountains
                   Of the Moon,
               Down the Valley of the Shadow,
                   Ride, boldly ride,"
                   The shade replied-
               "If you seek for Eldorado!"
