We have seen these mummies that came out of the Great Pyramid, have poked our way into the treasure room and have seen some of these recoveries which were made when the pyramid was entered. To show something of the interest the kings of antiquity had in their resting places, it is recorded on credible ancient authority that the building of this Great Pyramid occupied twenty years, and that three hundred thousand men were employed in the building. Ten years were occupied in the one task of quarrying the stone. Another decade passed by in the erection of the monument. Herodotus states that the men worked in groups of ten thousand, laboring three months at a shift. The records of Herodotus contain a description of the construction of earthen ramps up which the stones were skidded by means of wooden machines. The Cairo Museum contains a number of very valuable exhibits from this greatest of all burial mounds. So also has the second pyramid of Gheza, in turn, yielded its mummies, as have the others which have since been breached. We cannot ignore the great evidence given by the type of monument composed of the obelisks, the erection of which delighted the ancient conquerors. These consisted of enormous stone shafts that towered into the air sometimes to a distance of seventy feet. These great spires were engraved with the name of the monarch, a description of his greatness, and some of the more important records of his reign. In closing, we must not neglect to mention also the boundary markers that were so common in the Assyrian culture. These engraved stones, often illustrated with sculptured figures in high relief, are of unique importance not only because of their written records but also because of their ubiquity. Throughout all of the ancient world of Mesopotamia they seem to have been in general use. Since they were an important factor in deciding the title of a section of land, they were carefully made and preserved. The date factor is generally a certain year of the reign of a given king, and the historical information derived from monuments of this type is practically unlimited. (See Plate 16.) Also, since the ancients had no hinges, it was customary in constructing a door to have it turn upon a pivot. Beneath the door sill was a hollowed stone customarily called an ouch. This acted as a bearing which supported the weight of the door and enabled one man easily to swing a very heavy structure. These ouches were generally engraved with the name of the building, the purpose of the building and, perhaps, the cost and record of the construction. (See Plate 17.) From all these scattered sources, then, we gather together the unified testimony of multiplied thousands of men once dead who speak from the long silence of their forgotten era. Their united testimony is an unbroken chorus of assurance for those who are concerned over the integrity of the text of the Scripture.
