"With regard then to the rearing of the children they related so much as I have said: and I heard also other things at Memphis when I had speech with the priests of Hephaistos. Moreover I visited both Thebes and Heliopolis for this very cause, namely because I wished to know whether the priests at these places would agree in their accounts with those at Memphis; for the men of Heliopolis are said to be the most learned in records of the Egyptians."
- Herodotus Book II.3.1
