Cuneiform writing
Now, the earliest of the inscriptions which tell us anything about these people of Babylonia goes back to the time before the Semites had come up from Arabia in the south. Edim, or the plain of Babylonia, from which we may suppose that the name Eden, in Genesis, came, was probably then inhabited by those Sumerians of whom we know very little. We know little, but we find inscriptions by them, and the inscriptions are in a very curious form of writing, a writing which went on being used for thousands of years. It is called cuneiform, from "cuneus," meaning a wedge, because all the lines of the writing are inclined to go into the shape of a wedge.
You will remember something about the Egyptian hieroglyphic and picture writing. Probably all writing began in this way, with making pictures. Then it was found troublesome to make a picture of everything that you wanted to say, and a few dashes or lines, very roughly representing the thing, were used instead, and began to be understood as standing for a sign of that thing.
This wedge writing of the Babylonians doubtless began in this way. I say doubtless, because some of it is almost picture-writing, and the older the inscriptions the more like actual pictures of the thing as we see it the signs are. Thus, the sign which they made to mean heaven was something like this *, which we call an asterisk, from "aster," meaning a star. They made a drawing like a star to give the idea of heaven, because heaven is the place where the stars are. The rays, as we call them, of the star, were more wedge-shaped than the lines of our asterisk, but that is a small difference. It is said that when the "stilus," which is the tool they used for making the inscriptions, is used to make the mark of a line on wet clay, the shape into which that mark would naturally go is that of a wedge; they had much clay for their bricks, and very likely that is why we see this writing in the form that it has.
You may remember how we cited, as an instance of the way in which the Egyptians developed their writing, that we had first the picture of an eye, and then the picture of a bird, and, putting the eye before the bird, we got the idea "I see a bird." Now, in much the same way, in the wedge-writing we find that an arrangement of three upright wedges is taken as the sign which means "water." There is an arrangement of a good many wedges which is the sign that means "mouth," and this arrangement is in such a shape that it must make us think that it came from an original drawing of a mouth. So, having this sign for water and this other sign for a mouth, what these cuneiform writers did when they wanted to make a sign which should mean "drinking" was to put the sign for water inside the sign for mouth. A good idea!
But all this writing, so far, proceeded on the plan of making signs to represent things that you saw or the ideas that came from what you saw. And then, I imagine, it occurred to some inventive genius to say, "Suppose, instead of making these signs to represent things that we see, that we make them represent sounds—make them stand for the names that we call them by? Now, suppose we take the word 'dog': (only he, of course, would make use of the Babylonian sound, whatever it was, which they used for 'dog'). "Suppose we take the word 'dog,'" he said, "and suppose we take one of our signs, which we use to represent things, and let it stand for the first sound that we make in saying the word. Suppose that we take another sign to stand for the second sound, the middle sound, in the word, and a third sign to stand for the last sound."
"Well," the people to whom he suggested the idea might say, "you do not seem to gain much by that. It would be much simpler and easier to go on making the sign for a dog, as we always have done."
"Yes," he might answer, "that is quite true, so far as writing about a dog, and a dog only, is concerned, but the advantage that I claim for my idea is that these signs, which I say we might use to stand for the sound that we make when we say 'dog,' may be used over and over again, whenever we have to make those sounds. And we do not make a very large number of different sounds—not nearly so many as there are ideas and objects that we wish to write about. So, on my plan, we shall not need nearly so many signs as we have been using."
