The Mayans, just as the Egyptians, were Atlanteans, if we are to believe the legends. And, if we are to believe our eyes. Both their architecture and their art are similar, and their symbols would be understood by each other.
Although the last small part of Atlantis was submerged under the sea about 12,000 years ago, according to Egyptian priests, as reported by Plato, legend says that this vast continent, which later broke into fragmented islands, took about 850,000 years to disappear, following the initial warnings and disruptions. Of course, not all of it has disappeared. The Azores of today were mountaintops on Atlantis, and the Marshes of Tsaidam may also be a remnant of that ancient continent.
Older than the Chaldeans, who were master astronomers and astrologers, and the Babylonians, the Atlanteans, who have entered history as Egyptians, Romans, Greeks, Sicilians and other Mediterranean people, understood that astrology was nothing more than interplanetary chemistry. As psychology is to physiology, astrology is to astronomy. The old people, in fact, called astronomers night watchmen. But they imagined astrologers to be magicians.
The Mayan calendar, then, is of interest, although interpretations of coming events may be overly dramatized.
