The head of the MSA's ancient Egyptian department, Mohammed Abdel Maqsud, said the priest was clinging to an offering table that has two falcon heads, which represent Montu, and religious texts carved in hieroglyphs.
The second piece, made out of limestone, is larger and depicts one of the great temple scribes, "imn-hob", holding a sarcophagus and a statuette of Montu.
Construction of the temple began in the Middle Kingdom (1975-1640 B.C.) and was expanded during the successive Pharaonic dynasties until era of the Ptolemaic Kingdom (332-30 B.C.).
The experts from the French Institute for Oriental Archaeology in Cairo are working in the area in collaboration with France's University of Montpellier and a French-Egyptian centre for the study of the Luxor temples.
