Pablo Picasso was born in Spain in 1881. His father was an artist and also anart teacher. He gave little Picasso the first lesson in drawing. The boy showed great interest in it and learned it very quickly. Picasso drew so well that he won a prize — “Science and Charity” for his first important painting at the age of 15. Later he studied in several cities in Spain. But no one could teach him because he had known so much.

When he was 19, he visited Paris. At that time, Paris was the center of the world for artists. Everything in the painting world was new to Picasso. When he was 23, he moved to Paris to live and spent the rest of his life in France.

In his 80s, Pablo Picasso still worked like a young man. He kept on looking for new ideas and new ways to work. He never stopped painting all his life.

Pablo Picasso, one of the greatest artists in the world, died in 1973.

“可是到了冬天，那个坍塌了的白塔，又重新修好了，那个在月下唱歌，使翠翠在睡梦里为歌声把灵魂轻轻浮起的年青人，还不曾回到茶峒来。……这个人也许永远不回来了，也许‘明天’回来！”
