The Nag Hammadi library consists of twelve books, plus eight leaves of a thirteenth book. There are a total of fifty-two tracts. These are now kept in the Coptic Museum in Cairo, and, as the name suggests, are written in Coptic, although it is clear that the texts are Coptic translations of earlier Greek works.

Carl Jung and the Spiritual Problem of the Modern Individual

From https://academyofideas.com/2017/06/carl-jung-spiritual-problem-modern-in...

The Savior said to them: "I want you to know that all men are born on earth from the foundation of the world until now, being dust, while they have inquired about God, who he is and what he is like, have not found him. Now the wisest among them have speculated from the ordering of the world and (its) movement. But their speculation has not reached the truth.
The Nag Hammadi Library

Greek tradition reflects a meeting between Pythagoras and Zoroastrian Magi. In any case, there are many traces of Zoroastrianism in Pythagorean doctrine. In particular, there are similarities between the central Duality of Pythagoreanism and the dual Gods of Zoroaster (Ahura-Mazda and Ahriman)... 
When his wanderings were done (c.530), Pythagoras established a society of followers in Croton, Italy, where they learned Pythagorean Way of Life (Bios Pythagoreios) and were initiated by degrees into its mysteries. He wrote nothing down, but the poem of Parmenides (fl. 495), of which large fragments survive, seems to reflect Pythagorean ideas.
