Odyssey of the Gods:The History of Extraterrestrial Contact in Ancient Greece by Erich von Daniken takes a dispassionate look at Ancient Greece and challenges our assumptions about how Western Civilization evolved over the centuries. Could there have been otherworldly interventions to explain the facts presented in Odyssey of the Gods?
In Plato's writings, such as the dialogues Timaeus and Critias, one can read about the eradication of whole countries and cities, so that small groups survived in mountainous regions only. These survivors preserved the art of pottery, making clothing, simple weapons manufacture and hunting/gathering. The use of metals was taught to the survivors by the gods.
In the area of the "pyramids of Argolis" is the "block house." This is a square structure built of dressed stone beams. Parts of the construction are very similar to gigantic walls as far away as Peru. At both places, the stonework is not composed of monoliths cut at a 90 degree angle. The blocks are interjoined in a highly complex fashion with many corners — secure against earthquakes and violent earth movements. Even the pyramids have a structure; whereupon, each of three sides is counterbalanced during earthquakes so that the entire structure has withstood the centuries.
The machine of Anticythera is now in the Greek Museum in Athens. The metal parts consist of pure bronze or copper-tin alloys of varying compositions. There are small amounts of gold, nickel, arsenic, sodium, iron and antimony. The Greek letters gave absolute proof that the instrument had an astrological utility.
There were over 30 cogwheels of different sizes interconnected with one another and fastened to a copper plate by means of small axles. The mechanism had differential wheels which allowed star positions to be read off on a scale with millimeter lines. The mechanism allowed the moon's position in relation to the sun and earth to be computed.
