This chart shows several symbols used in Egyptian hieroglyphics (left) and in the early Semitic alphabet (center). Over time these symbols became transmuted into the B, G, Y, M and S of our own day. While the Semitic signs are barely distinguishable from their Egyptian predecessors, their function is radically different: The symbols represent the first sound in the name of the object depicted. As a result, a relatively small number of signs could be juxtaposed with each other to make a limitless number of words—the world’s first alphabet.
