Cheiro (William John Warner) was a renowned occultist, world-famous author, and a feared prophet and palm reader, as his predictions based on chiromancy always came true. He describes himself: "The success of my lifelong work with this art is based on the fact that while I primarily dealt with the lines and shapes of hands, I also made an effort to examine all aspects that could shed light on human life. For example, I also considered the elevations on the skin and the hair on the hand to obtain accurate indicators. Often, I found that people were skeptical of chiromancy simply because it was not explained to them in an understandable way. I publish this book with the hope that it will be seen as a useful and practical aid.".
