Swiss archaeologists have discovered the tomb of a female singer dating back almost 3,000 years in Egypt’s Valley of the Kings, Antiquities Minister Mohammed Ibrahim said on Sunday.

The rare find was made accidentally by a team from Switzerland’s Basel University headed by Elena Pauline-Grothe and Susanne Bickel in Karnak, near Luxor in Upper Egypt, the minister told the media in Cairo.

The woman, Nehmes Bastet, was a singer for the supreme deity Amon Ra during the Twenty-Second Dynasty (945-712 BC), according to an inscription on a wooden plaque found in the tomb.
