     The western alphabet, which is used in Europe, the Americas, Africa, Australia and New Zealand as well

as in other countries, originated in the Middle East. The people who gave the world this alphabet were the

Phoneacians, a people who established colonies all over the Mediterranean, including Carthage in Africa and

Gades in Spain. In their alphabet, the letters were represented by little pictures which represented sounds. The

Phoneacian A was aelph, which means"bull", and it was made from a little picture of a bull's head. The letter B

was beth which meant"house", and showed the round-roofed buildings which you can still see today in Syria.

     The Phoneacians had contact with another nation of sailors, the Greeks, with whom they fought and traded. The Greeks also started to use the Phoneacian alphabet. They changed the names, so aelph and beth became

alpha and beta. The shapes of the letters are the same, but they have been turned sideways. If you know any

Greek, you can try turning the letters around again, and see how they look. You will see that the curve on the

right of the Greek A becomes the horns of a little bull.

     Of course, the first two letters of the alphabet give it its name. Over the years there have been changes.

Latin developed an alphabet with some different letters to the Greeks, and other letters have been added since.

But really westerners are using the same system of writing which has served them so well for thousands of

years.
