One of the most astonishing collections in the world lives at the Harvard Museum of Natural History: the Blaschka Glass Models of Plants. The artists who produced this collection were the father and son Leopold and Rudolf Blaschka, the last in a long line of Czech glassworkers. From the years 1886 to 1936 they produced 4,300 models of botanical life. But that wasn’t all. They also created, for Harvard’s Museum of Comparative Zoology, 430 glass marine invertebrates—sea anemones, jelly fish, octopuses, marine worms, and more. Delicate and enchanting, glass invertebrates from Harvard will join objects from the Mystic Seaport Museum’s own collection, plus loans from other institutions, for a year-long exhibition. The 40-plus works on display are viewed through the prism of maritime history and science, and the exhibition includes sailors’ journals, rare books, watercolors, wet specimens preserved in jars, and depictions of marine invertebrates by contemporary artists. —Laura Jacobs
