Egypt ? Archaeologists unveiled the tombs Tuesday of a pharaonic butler and a scribe that have been buried for more than 3,000 years – proof that Egypt’s sands still have secrets to reveal.

Although archaeologists have been exploring Egypt intensively for more than 150 years, some estimate only one-third of what lies underground in Saqqara, site of the country’s most ancient pyramid and burial site of kings, has been uncovered.

“The sands of Saqqara reveal lots of secrets,” said Egypt’s antiquities chief, Zahi Hawass, as he showed reporters a 4,000-year-old mud brick tomb that belonged to a scribe of divine records, Ka-Hay, and his wife.

The tomb, along with the butler’s 3,350-year-old limestone grave and two painted coffins, one shown above, were discovered earlier this year near the famous Step Pyramid of King Djoser – the oldest of Egypt’s more than 90 pyramids.

Hawass said the mud-brick tomb unveiled Tuesday, which also featured wooden statues and a door with intricate hieroglyphic carvings – including one of the scribe and his wife – “could enrich our knowledge about the people who actually surrounded the kings of Saqqara.”
