Mesopotamia Books

“Berossos compiled his History from the temple archives of Babylon (reputed to have contained "public records" that had been preserved for "over 150,000 years"). He has passed on to us a description of Oannes as a "monster," or a "creature." However, what Berossos has to say is surely more suggestive of a man wearing some sort of fish-costume--in short, some sort of disguise. The monster, Berossos tells us: "had the whole body of a fish, but underneath and attached to the head of the fish there was another head, human, and joined to the tail of the fish, feet like those of a man, and it had a human voice ... At the end of the day, this monster, Oannes, went back to the sea and spent the night. It was amphibious, able to live both on land and in the sea ... Later, other monsters similar to Oannes appeared."
Bearing in mind that the curious containers carried by Oannes and the Apkallu sages are also depicted on one of the megalithic pillars at Göbekli Tepe (and [...] as far afield as ancient Mexico as well), what are we to make of all this? The mystery deepends when we follow the Mesopotamian traditions further. In summary, Oannes and the brotherhood of Apkallu sages are depicted as tutoring mankind for many thousands of years. It is during this long passage of time that the five antediluvian cities arise, the centers of a great civilization, and that kingship is "lowered from heaven." Prior to the first appearance of Oannes, Berossos says, the people of Mesopotamia 'lived in a lawless manner, like the beasts of a field.”
