Possibly the most important invention of the Egyptians was papyrus, which was the precursor of the paper of today. The clay tablets of the Babylonians were clearly much less adapted to the making of many records than was papyrus. One cannot readily imagine an edition of 300,000 newspapers like the _New York Times_, made out of clay tablets an inch in thickness, and sold on the streets by newsboys. Clearly the invention of papyrus was one so important that we cannot declare any invention as more important, except on the basis that (other factors being equal) the earlier an invention was the more important it was. To assume such a basis would, of course, be eminently reasonable; because the earlier invention must have supplied the basis in part for the making of the later. The invention of writing, for instance, was more important than the invention of papyrus. [Illustration: Villa of an Egyptian Noble] A curious invention of the Egyptians was the art of embalming the bodies of the dead, an art still practiced in civilized countries. It was prompted by their belief that the preservation of the body was necessary, in order to secure the welfare of the soul in the future life. This belief resulted further in building sepulchres of elaborate design, filling them with multitudes of objects of many kinds, decorating the walls with paintings, sculptures and inscriptions, and placing important manuscripts in the coffins with the mummies or embalmed bodies. The sepulchres of the kings were, of course, the largest and most elaborate of all; and of these sepulchres the grandest were the pyramids. By reason of the great care and labor lavished on tombs and sepulchres and pyramids, and by reason also of the dryness of the air in Egypt, and the consequent durability of works of stone, it has been from the tombs that many of the clearest items of information have come to us about old Egyptian times. The Egyptians excelled in architecture, and the greatest of their buildings were the pyramids. As to whether or not there was much invention devoted to those works, it is virtually impossible now to know. The probability seems to be that they could not have been produced without the promptings of the inventor, but that the progress was a slow and gradual march. It seems that there was a long series of many small inventions that made short steps, and not a few basic inventions that proceeded by great leaps. The Egyptians seem to have been the inventors of arithmetic and geometry. What men in particular should most be credited with inventing them, we do not know; but that some men were the original inventors the probabilities seem to intimate. For these sciences were creations just as actual as the steam engine, and could hardly have been produced save by similar procedures. [Illustration: The Pyramids of Gizeh]
