　　About 5 000 years ago, the Egyptians and other people in the Near East began to use pictures as a kind of writing. (20) They drew simple pictures or signs to represent things and ideas, and also to represent the sounds of their language. The signs these people used became a kind of alphabet. The Egyptians used to record information and to tell stories by putting picture writing and pictures together. When an important person died, scenes and stories from his life were painted on the walls of the place where he was buried. Some of these pictures are like modern comic strip stories. It has been said that Egypt is the home of the comic strip. (21)But, for the Egyptians, pictures still had magic power. So they did not try to make their way of writing simple. The ordinary people could not understand it. By the year 1000 BC, people who lived in the area around the Mediterranean Sea had developed a simpler system of writing. The signs they used were very easy to write, and there were fewer of them than in the Egyptian system. This was because each sign, or letter, represented only one sound in their language. The Greeks developed this system and formed the letters of the Greek alphabet. (22) The Romans copied the idea, and the Roman alphabet is now used all over the world. These days, we can write down a story, or record information, without using pictures. But we still need pictures of all kinds: drawing, photographs, signs and diagrams. Pictures help us to understand and remember things more easily, and they can make a story much more interesting.
