The Antiquities Ministry has made a string of discoveries since the beginning of 2017 in several provinces across Egypt - including the tomb of a royal goldsmith in the same area and belonging to the same dynasty, whose work was dedicated to the ancient Egyptian god Amun.
Studies reveal that the tomb was reused in antiquity, the ministry added.
"The tomb's owner is unknown yet but there are two possibilities".
Egypt on Saturday announced the discovery of two small ancient tombs in the southern city of Luxor dating back some 3,500 years and hoped it will help the country's efforts to revive its ailing tourism sector.
The names of the officials buried in the tombs remains unknown, as no inscriptions bearing the names of the tombs' occupants have yet been found.
Kampp 161, based on the wall paintings, engravings and inscriptions found inside, dates back to around the end of the reign of pharaohs Amenhotep II and his son Thutmose IV, around 1400 BCE. "The existence of the tombs of the 18th Dynasty was known, but it was the first time archaeologists entered them", he added.
Mostafa Waziri, the secretary-general of the Supreme Council of Antiquities and head of the Egyptian excavation mission, mentioned that both tombs were "baptized" by German archaeologist Frederica Kampp who originally discovered them.
An Egyptian guard monitors the entrance of a 3,500-year-old tomb where a mummy was recently discovered.
One tomb has five entrances leading to a hall, while the other has a six-meter burial shaft leading to four side chambers. The artifacts found inside were mostly fragments of wooden coffins.
Afterward, Anani headed to a nearby site where the famous Mortuary Temple of Hatshepsut is located to publicly open for the first time the temple's main sanctuary, which is known as the "Holy of Holies". "The first suggests that the tomb could belong to a person named "Djehuty Mes" as his name was engraved on one of the walls", Waziri said.
Alternately, it could belong to the scribe Maati, as his name and the name of his wife Mehi were inscribed on 50 funerary cones found in the tomb's rectangular chamber.
Scientists found a mummy, frescoes, clay pots and statuettes in the tombs, which are already being examined by experts to give more insight into the discovery.
The mission uncovered 100 funerary cones, painted masks, 450 statues carved in different materials and a small box shaped like a coffin.
