=Senṭ= or =Senṭȧ= is mentioned in connexion with a certain medical work which was either written or edited in the reign of Semti, the fifth king of the Ist dynasty. Nothing is known of Senṭ’s reign, but we find from the tomb of =Sherȧ=, a priest, that services were performed on behalf of his Ka or “Double” and that of his predecessor Perȧbsen. Sherȧ the priest probably lived at the end of the IInd, or at the beginning of the IIIrd, dynasty. A fine slab from his tomb is exhibited in the Egyptian Vestibule, No. 1. Of the remaining kings of the IInd dynasty, =Neferkarā=, =Neferkaseker=, =Ḥetchefa=, and =Bebi=, or =Tchatchai=, their names only have survived. Third Dynasty. From Memphis. _About_ B.C. 3966. The greatest of the kings of this dynasty was =Tcheser=, or =Tcheser-sa=, who is renowned as the builder of the famous =Step Pyramid= at Ṣaḳḳârah. This pyramid is about 200 feet high, and has six “steps,” 38, 36, 34½, 33, 31, and 29½ feet high respectively; the lengths of its sides at the base are: north and south, 352 feet, east and west 396 feet. A tomb of Tcheser, who has been identified with this king, was discovered at Bêt Khallâf in 1901. Details of his reign are wanting, but, according to a legend preserved on a rock stele on the Island of Sâḥal in the First Cataract, a =Seven Years’ Famine= came upon Egypt in his time, and want and misery were universal. Greek tradition ascribed to Tcheser great medical knowledge, and he is said to have been a patron of literature. Among the objects of this king in the British Museum may be mentioned the fragment of a slate vase (Table-case L, No. 169), and the very interesting small =glazed tiles= (Nos. 208, 209, in the same case; and see Table-case K in the Fourth Egyptian Room, Nos. 863-869), which were found inlaid in the wall of the doorway in the pyramid of King Tcheser.
