In developing the art of writing itself, much progress was effected in both countries, and many improvements were made in the art itself that must have been due to that lower order of invention which consists in improving on things already existing. In addition, invention was employed in devising and arranging means for preserving the writings in an enduring form. In Babylonia, this was done by making the writing on soft tablets of clay about an inch in thickness, that were afterwards baked to hardness. In the case of records of unusual importance, the precaution was sometimes taken of covering the baked inscription with a thin layer of clay, making a duplicate inscription on this layer, and then baking it also. If afterwards, from any cause, the outside inscription was defaced, it could be removed and the inside inscription exposed to view.
In Egypt, the writing was done on sheets of papyrus, made from a reed that grew in the marshes. To devise and make both the baked clay tablets and the papyrus, it is clear that invention had to be employed; for nothing exactly like them existed in nature. Thus the invention of the art of writing was supplemented by the invention of the art of preserving the records that writing made. The act of writing would have been useful, even if no means had been invented for preserving the things written; even if the things written had perished in a day. But the importance of the invention of writing was increased ten thousand fold by the invention of the means for preserving the things written; because without that means it would have been impossible by any process of continual copying of tablets to keep at hand for reference that library of records of the past on which all progress has been based, and from which every act of progress has started, since some inventor of Babylonia invented baked clay tablets and some inventor of Egypt invented papyrus.
It may be objected that there is no reason for assuming that any one man invented either; that each invention may have been the joint work of two men, or of several men. This of course, is true; but it does not minimize the importance of either invention, or the credit due to the inventors. It simply divides the credit of each invention among several men, instead of giving it all to one. It is a notable fact, however, that, although some inventions have been made by the joint work of two men, and although some books have been written, and some music has been composed by two men working in cooperation, yet such instances have been rare.
Many men combine to do constructive work of many kinds, and millions combine to work and fight together in armies; and it is an interesting fact that the working together of many men has been made possible by inventions, such as writing and printing. Yet there is hardly any other kind of work that is so wholly a "one man job" as inventing. The fact that only one man, as a rule, makes a certain invention, or writes a certain book, or composes a certain musical piece, or does any other inventional work, seems to spring naturally from the original fact that an invention begins with a picture made by imagination on a mind. Now a picture so made is an individual picture in an individual mind. If the picture is allowed to fade, or if from any cause the mind that received it does not form it into a definite entity, no invention is made. If, on the contrary, the mind develops the dim picture into a definite entity of some kind, that mind alone has made that invention; even if other minds improve it later by super-posing other inventions on it.
It is true that sometimes a man who receives from his imagination a mental picture of some possible invention will communicate it to another man, and that other man will contribute some constructive work, and make the dim picture into a reality; so that the complete invention resulting will be the joint product of two men. It seems to be a fact, however, that these dim pictures have rarely been disclosed while in the formless period, and that almost every invention of which we know the history, was made by one man only.
It need hardly be interjected here that we are discussing inventions only, and not the acts of making inventions practicable in the sense of making them useful or commercially successful. At the present day, there are few inventions indeed, which even after having been completed as inventions, need no modification at the hands of the engineer and the manufacturer, before they are suitable to be put to practical use.

That the Babylonians realized the importance of their invention is proved by the fact that their baked tablets were carefully preserved, and that in some cities large libraries were built in which they were kept, as books are kept in our libraries at the present day. When the expedition of the University of Pennsylvania made its excavations near the site of the ancient city of Nippur, in the southern part of Babylonia near the city of Babylon, a library was discovered that contained more than thirty thousand tablets.
