Gnosticism is part of the 'mystery schools', these were secret organizations throughout the ancient world that continue today with freemasonry.
Egypt had one where they would play out the death and ascension of Osiris, killed by set (god of hte israel desert).
In greece they had multiple versions of this, including a goddess named Persephone falling to the underworld and needing to be restored, similar to sophia. this exact mystery school was said to have its secrets revealed by the playwright aeschylus, who wrote a play called prometheus bound about 400 years before jesus was born hinting at his coming to save the greek peoples.
the stories and legends always existed, they just change form depending on what mythologies are legally acceptable, going from ancient greek to christian gnostic.
but it was always the same history and prophecies of the future they were passing down.
in their intense meditations they did seem to make contact with the higher dimensions of spiritual beings.
