In the 1st edition, published in 1962, he spoke to that perennial reader he gently called "the troubled layman." His opening paragraph revealed his sympathy: "Why is this supposed to be art?" he quoted rhetorically. "How often have we heard this question asked--or asked it ourselves, perhaps--in front of one of the strange, disquieting works that we are likely to find nowadays in the museum or art exhibition?" Keeping that curious, questioning perspective in mind, he wrote a history of art from cave painting to Picasso that was singularly welcoming, illuminating & exciting. Sojourning thru this book, a reader is offered every amenity for a comfortable trip. Because he never assumes knowledge on the part of the reader, a recent immigrant from Mars could comprehend Western art from this text. The only assumption the Jansons have made is that with a little guidance everyone can come to understand the artifacts that centuries of architecture, sculpture, design & painting have deposited in our paths. Countless readers have proven the Jansons right & found their lives enriched in the process.
