As promised, here are some references:
This is from Timothy Freke and Peter Gandy’s Hermetica:Thomas Taylor, the first English translator of Plato's texts, believed that Plato was initiated into the Egyptian mystery schools at the age of 49, in one of the subterranean halls of the Great Pyramid of Giza.  Plato's work was greatly criticized for revealing many of these Hermetic mysteries in his writings available to those outside the mystery schools.  If these assertions are correct, then it would be correct to call Plato's work Hermetic and not the Hermetists Platonic.
and ...Casaubon particularly claims that the Hermetica plagarised the Timaeus – a work written by the Greek philosopher Plato in the 5th century BCE. Like the Hermetica, it includes the doctrines of astrology and reincarnation. Yet these ideas played no part in early Greek religion, so where did they come from?
The answer is ancient Egypt. Over a hundred years before Plato, the Greek sage Pythagorus had set out on a journey to acquire the knowledge of the world. This led him to Egypt where he spent twenty-two years in the temples being initiated into the religion of the Egyptians. According to the ancient Greek scholar Diogenes Laertius, Plato purchased three books of Pythagorean doctrines based on Egyptian wisdom, and these he adapted into Timaeus.
The similarities between the works of Plato and the Hermetica are not surprising, therefore, since many of Plato’s ideas were direct descendants of ancient Egyptian philosophy.
And this from Herodotus:While Casaubon was writing  very little was actually known about ancient Egypt. The hieroglyphs themselves were not translated until two centuries after his death. Consequently, many modern scholars now believe that he was wrong to see the Hermetic philosophy as a second century invention, especially since the discovery of the pyramid text of Saqquara at the end of the last century. These hieroglyphs are over 5000 years old and yet contain doctrines that are identical to those expounded in the Hermetica.
The Egyptians are religious to excess, beyond any other nation in the world ... they are meticulous in everything which concerns their religion ... It was only, if I may put it so, the day before yesterday that the Greeks came to know the origin and form of the various gods ... The names of all the gods came to Greece from Egypt ...for all the names of the gods have been known in Egypt from the beginning of time.
