Cartouche of Ptolemy, or Ptolemais.—The hieroglyphs composing the name are—a square cross-barred, which represents P; a hemisphere, T; a knotted ribbon, O or U; a lion, L; an open quadrangle, M; two leaves of a plant, I or AI; the back of a chair, S; making together, PTOLMAIS; the vowel _e_ being lost. ] [Illustration: Cartouche of Cleopatra.—The hieroglyphs are—an angle, Q or C; lion, L; leaf, A short, for E; knot, O or U; square cross-barred, P; eagle, A; hand, T; mouth, R; eagle, A; then follow an egg; and a hemisphere t, which indicate sex, and signify daughter. The whole together making CLEOPATRA, a daughter. ] The decipherment of Egyptian hieroglyphs was a curious accident, and, at the same time, an important step in the science of Egyptology. The French, in the year 1799, while digging the foundation of a fortress at Rosetta, exhumed a slab of black stone—a precious relic, as it proved to be, now carefully preserved in the British Museum.[37] On this stone was carved an inscription in three languages:—Hieroglyphic, the sacred tongue of Egypt; Demotic, the common language; and Greek. The inscription itself is a decree of the priests in honour of Ptolemy V., Epiphanes. Twenty years elapsed before the value of this writing was realised, although the Greek inscription had not failed to inform its readers that its two companions were translations of itself. The inclusion of royal names and royal titles within an oval had been made known by Zoëga some years before; and, comparing the Greek with the hieratic characters, the signs which indicated the name of Ptolemy were next made out. But it did not suffice to identify the emblazonment of Ptolemy alone; it needed the genius of Champollion to discover that the signs represent the letters of the alphabet. The word Ptolemy had supplied him with certain fixed signs, when a happy chance presented him with the cartouche of Cleopatra as certified by a Greek inscription on the base of an obelisk from Philæ. Comparing the signs of the two ovals, he was put in possession of three consonants and two vowels, which were identical in both, and corresponded as to position in the construction of the words. The three consonants were P T L, and the vowels E and O. Further research supplied him with the ovals of Berenice, Alexander, Cæsar, Tiberius, Trajan, and Hadrian; which together made up a complete alphabet. He was now in a position to read names in Greek when expressed by hieroglyphic signs. The next step was to convert the signs of the hieroglyphic text into words; and these he found to be Coptic, the national language of Egypt. All this seems to be simple enough when it is known; but Champollion had yet to discover that some of the signs were simply alphabetical, others syllabic, and others again symbolic; moreover, that the three kinds of
