One hundred years ago, a beached whale would have been greeted by a mob wielding flensing knives; today, people bring harnesses and boats to help it return to the sea. The whale is one of the most awe-inspiring and intelligent animals in nature, sharing a complex relationship with humans that has radically evolved over the centuries. Joe Roman offers in Whale a fascinating and in-depth look at the cultural and natural history of these majestic aquatic mammals. From the Biblical prophet Jonah to Moby-Dick to recent discoveries of cetacean songs and culture, Roman examines the whale's role in history, art, literature, commerce, and science. Whale features vibrant illustrations, ranging from Stone Age carvings to full-color underwater photographs, which vividly bring to life the rich symbolic meanings surrounding the whale. Roman also examines the ecological and evolutionary history of the whale as well as contemporary issues of conservation. Whale is an engaging volume that will appeal to all those interested in the important role that these kings of the ocean have played in human culture.
