The present century has been a disappointing one for comets, but past centuries often featured spectacular, unforgettable comet shows that dominated the night (and even daytime) sky for months: comets that outshone Venus or even the Moon, whose spectacular tails stretched more than halfway across the sky or were weirdly split, and whose apparition was held responsible for everything from wars to unusually good wine vintages. Published to coincide with the first naked-eye appearance of Comet Hale-Bopp, perhaps our own "comet of the century", this book is a guide to comet facts and lore throughout history.
