Silver bracelets from the Egyptian tomb of Queen Hetepheres I (2600 BCE) suggest trade between the Greek and Egyptian civilizations. Silver sources from this time in Ancient Egypt have not been documented:
Queen Hetepheres was the wife of King Sneferu and mother of Khufu around 2600 BCE. In is truly amazing to think that there was some trade (either direct or thru an intermediary) between Ancient Greece and Ancient Egypt.
