Instead of the established idea, that "America" derived from the name of the Italian explorer Amerigo Vespucci, I propose you an alternative historical version - which may in fact be, the real one.

The worship of the Serpent Gods - The oldest 'religion' on Earth

Quoting the book Secret Doctrine by H. P. Blavatsky, it states that worship of the dragon and the sun were universal on the earthplane.

"The tradition of the Dragon and the Sun is echoed in every part of the world.…There was a time when the four parts of the world were covered with the temples sacred to the Sun and the Dragon: but the cult is now preserved mostly in China and the Buddhist countries (p. 378-9, V. II)." The dragon, however, is not the middle age concept of a beast with wings breathing fire, but is, in reality, a snake.

Welcome to Amaruca, Land of the Serpent Gods!

In his book, "New World Order: The Ancient Plan of Secret Societies", William T. Still shows that America was called initially "The Land of the Plumed Serpents" by the Indians of Peru.

James Pyrse researched an article written in the Theosophical Society magazine entitled "Lucifer", which gave insight into the word "America." He says that the chief god of the Mayan Indians in Central America was Quettzalcoatl / Kukulkan ("Plumed Serpent", "Feathered Serpent"). In Peru this god was called Amaru and the territory known as Amaruca.

Pyres states: "Amaruca is literally translated 'Land of the Plumed Serpents' (p. 45) - (Variation: 'Land of the Great Plumed Serpents)." He claims that the name of America was derived from Amaruca, instead of after the explorer Amerigo Vespucci. This further proves that serpent worship was common throughout all cultures.
