This work sets sail from the colonial voyages of the eighteenth-century naturalist Joseph Banks and from the long migrations of plants and animals. In the 1930s, officials of the Japanese colonial government imported an African snail from Singapore to Taiwan; a being absent from the island’s ecologies took hold as an introduced species under unfamiliar conditions. Grounded in the Indigenous heritage of Chang En-Man, the piece gathers members of the Paiwan people into an ancient chant that begins with a speculation on Austronesian and human origins and gives voice to the story of the snail. Within layered histories that shuttle like ships—crossing and interlacing—the chant traces a life arriving from elsewhere, seeking where to settle, and, as environments continue to shift, changing shape in order to endure.
