The concept was invented by the ancients: These are things to be experienced in one's lifetime. Their choices were man-made works on a monumental scale, pyramids and temples and tombs of surpassing grandeur. This notion of Seven Wonders proved irresistible, and, during the Middle Ages, another list was created. In the Modern era, yet another. There are, as well, Natural Wonders and Animal Wonders. Here, in a single LIFE volume, are all of them, each worthy of the original admonition: Don't Miss This! Loaded with full-color, glossy photographs and captivating commentary characteristic of LIFE books.
