Don..many of the major Gods of Egypt can be traced back to the Pre and Protodynastic eras ie between 3000 & 5000 BCE
".. Khnemu was originally a water-god, and as such he is shown with water flowing over his outstretched hands and wearing a jug on his head above his horns. His name comes from the root, khnem, "to build". ...
Now in many of Nicolas Poussin's paintings he has the water god shown and always water is pouring out of the jug. Is this the god he refers to ?"
Do you have evidence that Poussin was familiar with Egyptian Language and hence Beliefs??
WE couldn'[t read that language at all until the 19th century and much of what we know of the Pre and Protodynastic is a result of the work begun by Petrie et al at Naqada and Abydos...250 years after Poussin's death!!!!
