The word mummy is said to be derived from “mourn,” a kind of wax used in the process of embalming. This process would seem to have been first employed during the eleventh dynasty, about 3,000 years before the Christian era, and to have been practised until the 6th century A.D. Mariette notes differences in the appearance and qualities of the mummies in accordance with their source—from Memphis or Thebes, or their preparation in more recent times. The Memphite mummies are extremely dry, break easily, and are black in colour; those of Thebes are tightly bandaged, yellow and flexible, bending easily, and sometimes preserving so much softness as to admit of being indented by pressure: whereas, in later times, the bodies were saturated with a kind of turpentine from Judea, and became heavy, compact, the bandages seemingly identified with the flesh, and so hard as only to be broken with violence. The Memphite mummies were often filled with amulets and scarabæi, and by their sides, or between their legs, was placed a papyrus, a copy of the Book of the Dead. On the Theban mummies were scarabæi and rings, which were worn on the fingers of the left hand. [Illustration: A pylon or doorway of a house or temple.] The essentials of a tomb, for such as could afford the expense, were, a deep quadrangular well in the rock; in the side of this well was a smaller cavity for the deposit of the mummy, or of the mummy-case; after which, the entrance of the cavity, or grave, was carefully walled up; next followed a chamber in which mourners and friends could assemble; and after that a portal, or exterior entrance, by which admission might be obtained. It is easy to understand how this simple design may be amplified until an entire rock of considerable magnitude has been hollowed out into numerous chambers; how these chambers may be ornamented with columns and sculptures; how the portal may assume an architectural form, and become a pylon, and the front of the rock be carved into columns and statues of imposing grandeur and beauty. Indeed, there would seem—as in fact is the case—no bounds to the intricacy and extent of the sanctuary and its chambers, the elegance and decoration of the appurtenant halls, and the magnificence and grandeur of the pylonic front. We should be pleased to imagine that the first efforts of man practised on the rocks, and thence transferred to the plain, were the early origin of Egyptian architecture, were we not aware of the fact, that the work of the mason makes its appearance seemingly contemporaneously with that of the wonderful excavations, of which so many examples are to be met with on the banks of the Nile.
