This book has been nominated for The Mountbatten Award for Best Book in the Maritime Media Awards 2021. The Routledge Companion to Marine and Maritime Worlds, 1400‒1800 explores early modern maritime history, culture, and the current state of the research and approaches taken by experts in the field. Ranging from cartography to poetry and decorative design to naval warfare, the book shows how once-traditional and often Euro-chauvinistic depictions of oceanic ‘mastery’ during the early modern period have been replaced by newer global ideas. This comprehensive volume challenges underlying assumptions by balancing its assessment of the consequences and accomplishments of European navigators in the era of Columbus, da Gama, and Magellan, with an awareness of the sophistication and maritime expertise in Asia, the Arab world, and the Americas. By imparting riveting new stories and global perceptions of maritime history and culture, the contributors provide readers with fresh insights concerning early modern entanglements between humans and the vast, unpredictable ocean. With maritime studies growing and the ocean’s health in decline, this volume is essential reading for academics and students interested in the historicization of the ocean and the ways early modern cultures both conceptualized and utilized seas.
