D. Pedro II... rei de Espanha e Portugal no século XVI???

"Since the 16th century, adventurers have been obsessed with finding gold and silver mines in Brazil, particularly the Lost Mine of Muribeca.

Roberio Dias owned a rich silver mine somewhere in the interior of Brazil, worked by Indians and rumored to be thousands of years old.

Roberio Dias' father was a half-Indian named, Muribeca. He had inherited the mine from his father, a Portuguese man and the survivor of a shipwreck who lived with a friendly Indian tribe and who later married an Indian woman. Although Dias was very wealthy, he was nevertheless a commoner, and worse, a mestizo - a name given to someone whose blood is part Indian.

One thing Dias always wanted in life was a title, a certificate of nobility. And so he travelled to Madrid and proposed a deal to the King (of Spain and Portugal at the time) Dom Pedro II. He offered the King all his riches from his splendid mines in return for the title of 'Marquis of the Mines.'

Dom Pedro II refused. Instead, Dias' certificate was sealed and ordered to be given to Dias when the location of the mines were disclosed. But enroute to the mines, Dias convinced the ship's captain to open the orders before they reached Bahia. Much to his surprise and dismay, Dias learned he was not to be the Marquis of the Mines after all. Contrary to what the King had promised, the sealed orders declared that the King had dispersed a military commission to the area with Dias as 'captain.' Understandably, Dias refused to give up the location of the mines.

Dias was imprisoned in a dungeon in Salvador for two years. But still, he refused to talk. Eventually, he was allowed to buy his freedom, and in 1622 he died. Fortunately, the secret location of the mines went to his grave with him.

Many expeditions were launched to find these mines, and most never returned."
