The Quest of El Dorado

An alien Indian, hailing from afar,
Who in the town of Quito did abide.
And neighbor claimed to be of Bogata,
There having come, I know not by what way,
Did with him speak and solemnly announce
A country rich in emeralds and gold.

Also, among the things which them engaged,
A certain king he told of who, disrobed,
Upon a lake was wont, aboard a raft,
To make oblations, as himself had seen,
His regal form overspread with fragrant oil
On which was laid a coat of powdered gold
From sole of foot unto his highest brow,
Resplendent as the beaming of the sun.

Arrivals without end, he further said,
Were there to make rich votive offerings
Of golden trinkets and of emeralds rare
And divers other of their ornaments;
And worthy credence these things he affirmed;
The soldiers, light of heart and well content,
Then dubbed him El Dorado, and the name
By countless ways was spread throughout the world.
