Ongoing excavations include protection, site management, and conservation of these structures in Abydos, Egypt. Credit: Josef Wegner / Penn MuseumAn international team of archeologists have discovered a massive tomb that belonged to one of ancient Egypts earliest pharaohs. However, the rulers identity remains a mysteryas do many details of his long-lost dynasty.The existence of an Abydos Dynasty was first confirmed in 2014 after archeologists uncovered the tomb of King Seneb-Kay. The newer crypt, discovered in January, is estimated to have been constructed during the Second Intermediate Period (1640-1540 BCE), an era of political and economic instability that temporarily broke a unified Egypt into multiple rival kingdoms.The burial site was located almost 23 feet beneath Abydos.

Ancient Egyptian mythology held that Abydos served as the burial place for Osiris, god of the underworld. Many of historys earliest pharaohs also chose to be interred there inside a sprawling royal necropolis near Anubis Mountain.The team of researchers from Penn Museum in Philadelphia working with archeologists from the Egyptian Ministry of Tourism and Antiquities used tools including magnetometry, photogrammetry, and remote sensing to map the spacious burial complex. Additional excavation work has already revealed architectural and decorative similarities to Seneb-Kays tomb, leading experts to theorize it may have belonged to a predecessor. But further details, including even his name, still elude archeologists.]Credit: Josef Wegner / Penn Museum Credit: Josef Wegner / Penn Museum The kings name was originally recorded in painted scenes on plastered brickwork that decorated the entrance to the limestone burial chamber, Josef Wegner, curator of Penn Museums Egyptian Section and a University of Pennsylvania Egyptian Archaeology professor, said in the museums announcement on March 27.Painted scenes include depictions of the goddesses Isis and her sister Nephthys, as well as hieroglyphic texts on yellow bands. According to Wegner, however, it appears that ancient tomb robbers damaged the texts during their expeditions into the grave.Credit: Josef Wegner / Penn Museum Credit: Josef Wegner / Penn Museum There are multiple potential contenders for the tombs owner. Two kings in particular, Senaiib and Paentjeni, have dedicated monuments elsewhere in Abydos but their gravesites remain unaccounted for. Information gleaned from the tomb also confirms the existence of other early Egyptian kings in the surrounding enclosure.Excavation work will continue over the course of 2025, primarily in the new focal area at Anubis Mountain spanning over 100,000 square-feet. The Adybos marks the second discovery of an Egyptian kings tomb this year. In February, archeologists confirmed the location of Thutmose IIs crypt, marking one of the biggest ancient Egyptian discoveries since King Tutankhamun in 1922.
