With the accession of =Seneferu= one of the most important periods in the history of Egypt opened, and it was marked by the =conquest of the Sûdân= and the =Sinaitic Peninsula=, by the building of the =Pyramids=, and by the production of bas-reliefs, sculptures, wall-paintings, etc., which for fidelity to nature and delicacy of execution were never surpassed. Several of the earlier kings of Egypt had trade relations with the natives of Sinai who worked the famous copper and turquoise mines of Wâdî Maghârah; but Seneferu invaded the country and conquered it, and cut reliefs on the rocks in which he is represented clubbing the rebellious natives. He was the first to group four of the royal titles within a cartouche thus: 𓍹𓐼𓆥𓅒𓎟𓌷𓐰𓏏𓅉𓋴𓄤𓂋𓅱𓐽𓍺. He also =raided the Sûdân=, and captured, as we learn from the Palermo Stele, 7,000 men, _i.e._, slaves, and 200,000 animals, _i.e._, oxen, cows, goats, etc. The men were, no doubt, brought to Egypt and made to labour there on the king’s works. During the reign of Seneferu, Egypt was invaded by certain Eastern tribes by way of the desert; and the country seems to have suffered from a famine. Seneferu was probably buried in the =Pyramid= of =Mêdûm=, which is called the “False Pyramid,” and is of an unusual shape; it is about 115 feet high, and consists of three stages, which are 70, 20, and 25 feet high respectively. He also built a pyramid at Dahshûr. His queen was =Mert-tefs= 𓌻𓐰𓂋𓐰𓏏𓏏𓐰𓆑𓋴, who survived him and was living during the reigns of Khufu and Khāfrā; a limestone false door from her tomb is exhibited in the Egyptian Vestibule, No. =7=. The governor of Seneferu’s pyramid at Mêdûm was Ka-nefer (for his sepulchral stele see the Egyptian Vestibule, No. =8=), to whose memory a pious son set up the memorial tablet No. =9=.
