In this exquisitely illustrated portrait, poet and artist Miek Zwamborn shares discoveries of seaweed’s history, culture, and science. We encounter its medicinal and gastronomic properties and long history of human use, from the Neolithic people of the Orkney islands to sushi artisans in modern Japan. We find seaweed troubling Columbus on his voyages across the Atlantic and intriguing Humboldt in the Sargasso Sea. We follow its inspiration for artists from Hokusai to Matisse, its collection by Victorians as pressed specimens in books, its adoption into fashion and dance, and its potential for combating climate change, as a sustainable food source and a means of reducing methane emissions in cattle. And, of course, we learn how to eat seaweed, through a fabulous series of recipes based around these “truffles of the seas.”
