The Golden Bough by Sir James George Frazer is a groundbreaking study of mythology and religion. It explores the evolution of human belief from magic to religion and science. Frazer uses the legend of the Golden Bough, a sacred sprig found in the grove of the goddess Diana, to illustrate his theory. He argues that early humans believed in magic and supernatural forces to explain the world around them. Over time, these beliefs evolved into religion, and eventually, science. The Golden Bough is a complex and challenging work, but it remains an important contribution to the study of human culture.
