Ancient Egypt

The Ancient Egyptian civilization is considered the first and foremost of cultures. From approx. 3150 BC with the political unification of Upper and Lower Egypt under the first pharaoh, the history of ancient Egypt occurred in a series of Kingdoms: the Old Kingdom of the Early Bronze Age, the Middle Kingdom of the Middle Bronze Age and the New Kingdom of the Late Bronze Age. Egypt reached its pinnacle during the New Kingdom, in the Ramesside period. From Ancient Egypt, came classical writings and treatises which we know today as the Coffin Texts, the Pyramid Texts, Amduat, Egyptian Book of the Dead, etc. The Ancient Egyptian culture, traditions, rituals and religion served as the source and foundation for almost all subsequent traditions, cultures and religions, East and West.

Ancient Egyptian Sayings: Man, know thyself, and thou shalt know the Gods.
Ancient Egyptian Sayings: The body is the temple of the God within you; therefore it is said, ‘Man: know thyself.
Coffin Texts, Spell 848: You are one who knows yourself.
