Firstly, I don't think that all art is beautiful. Sometimes it's unpleasant or just plain boring! And not all art is useful either. Some paintings are so big you can't hang them on a wall and some sculptures are impossible to sit on. But I do believe that art is important. It can tell us what the world was like in the past, or what the artist was thinking when he or she made it. In this way, art can be like a historical document or a personal statement. For example, when I look at my friend's paintings, I can see her personality in them - they're very lively and colourful, just like her.
