As regards the original sites of the obelisks, none are found on the west bank of the Nile, neither are any pyramids found on the eastern bank of Egypt Proper; this caused Bonomi to think that obelisks were intended as decorations to the temples of the living, symbolized by the rising sun, and pyramids decorations of the temples of the dead, symbolized by its setting. The greater number of obelisks are engraven on the four faces; some are engraven on one face only, and some have never been inscribed. Some of the faces are engraven in one column, some in two, and some in three columns. In some instances the side or lateral columns have been additions in after times, in different and inferior styles of engraving; and in some instances the name of the king, within the oval or cartouche, has been erased and another substituted. The inscriptions are hieroglyphic or sacred writing, which have been unintelligible till within the last few years. The French occupation of Egypt commenced that discovery, which has been perfected by the key of Young and the alphabet of Champollion--though mainly perhaps indebted to the Rosetta Stone, found in 1799, engraven in three characters, hieroglyphic, Demotic and Greek. The more ancient inscriptions are beautifully cut, and as fresh as if just from the tool, and are curiously caved inwardly, and exquisitely polished. It would take too much of your space and of my time to give a history of the progress of this wonderful discovery, by which we now know more of the Egyptian history before the time of Abraham than of England before Alfred the Great, or of France before Charlemagne. Some of these monuments are considered to date as far back as 2,000 years before the Christian era. It is sufficiently evident, from the small number that are known to exist, that they were a most costly production, requiring a long time for their completion, and the most elaborate skill of the most perfect sculptors to execute. Bonomi, to whose indefatigable research, and clear and positive style of writing, and condensation of his knowledge I am indebted, out of his papers read before the Royal Society of Literature (of which I am a member), gives us an account of all the known obelisks.
