here is a good quote from Herodotus a greek historian:
The Egyptians appear to have reversed the ordinary practices of mankind. Women attend markets and are employed in trade, while men stay at home and do the weaving! Men in Egypt carry loads on their head, women on their shoulder. Women pass water standing up, men sitting down. To ease themselves, they go indoors, but eat outside on the streets, on the theory that what is unseemly, but necessary, should be done in private, and what is not unseemly should be done openly.
(Herodotus II: 33-37)
