Serpents in the Sky, serpents on Earth
Where did this wealth of astronomical and geodetical knowledge come from to the ancient Khmer? One immediate source is India. One shall remember the legends of the birth of the Khmer empire and the mysterious ceremony of the Deva-raja. The ties between the ancestors of the Khmer empire – the kingdoms of Funan and Chenla – and India date back to at least the 5th Century BC, at a time when the major trade routes between South-East Asia and the Mediterranean reached as far as Kattigara, in the present day Mekong delta (where hoards of Roman coins have been found at major Oc Eo sites, testifying very active East-West trade relationships). Additional influences may have come from the island of Java, ruled by the powerful Saliendra dynasty of Borobodur. Yet a third element appears in Khmer legends and tales of the origins of Angkor, the Nāga.
According to Hindu and Cambodian beliefs, the Nāga were a powerful reptilian race of serpent-like creatures which once ruled from a vast island-continent in the Pacific and later retreated into the underground. Indeed, one can find depictions and statues of Nāga almost everywhere at Angkor, on the balustrades of the temples or as protectors of the sacred places. The ancient Khmer expressed the myth of their origins through the union of an Indian prince Kaundinya and a beautiful Nāga princess, the daughter of the King of the Nāga, who dwelt in a Mountain called Kok Thlok.
One famous account of 13th Century life at Angkor from the Chinese diplomat Zhou Daguan tells of a powerful genie living in the pyramid temple of Phimeanakas (the “Palace of Heaven”). Every night the genie would take the form of a beautiful serpent-woman to sleep with the King. Terrible ruin would have befallen the kingdom had the King missed even one of his nightly appointments. Another account dealing with the end of Angkor recounts the story of the “Leper King”, who was cursed with leprosy after killing a Nāga. This same episode was also considered as the cause of the decline and fall of Angkor.
In ancient cultures, the Serpent was also a powerful symbol of the subterranean world and of telluric currents. As such, it may come as no surprise that Angkor allegedly occupies a very important spot in the Earth’s geomagnetic grid. According to researcher Jim Alison , Angkor is linked to a number of ancient sites through a network of coordinates of latitude and longitude. These sites include the Great Pyramid of Giza, Easter Island, Machu Picchu and the Nazca lines of South America, and the ancient cities of Petra, Persepolis and Mohenjo Daro. Also, Angkor is significantly located at 72° of longitude East of Giza (when one takes the meridian of Giza as the prime meridian to which is assigned longitude 0°), and 144° West of Easter Island – which is also 144° East of Giza.
Even though some of these speculations may seem too far-fetched, many other clues and symbols seem to link Angkor with ancient Egypt and the other major pyramid-building civilizations of antiquity. The very name of Angkor, supposedly a corruption of the Sanskrit Nagara (meaning City), bears striking similarities to the Egyptian hieroglyphic Ankh-Hor , meaning “The God Horus lives”. The giant Lingas located in most of the Angkor temples are reminiscent of the Egyptian Benben or the Greek omphaloi, significantly located at places of geodetic relevance. Also, similar to Egypt some divine architect was apparently involved in the construction of Angkor Wat and the major Angkorian monuments (Viskakarman, the architect of the Gods, who was later tributed divine honors just as his Egyptian counterpart, Imhotep).
It is also a curious coincidence that about the same time when Angkor was built, an authentic surge of monumental construction took place in very distant parts of the World including the Gothic cathedrals of Europe and the great Maya pyramids (the latter bearing an uncanny and as of yet unexplained similarity to Cambodian pyramids, more than half a world away).
