Archaeological excavations of Tell Edfu, ongoing for the last 16 years, have revealed some interesting information about how people lived in the Old Kingdom – see https://phys.org/print437211849.html … going back to the second half of the 3rd millennium BC. Edfu is in southern Egypt (or what was known as Upper Egypt) and finds from the 5th century are currently being investigated. Edfu was an important post for expeditions into the Eastern desert in search of metals and stone. The Red Sea coast was just 125 miles to the east.
