In this collection of poetry, Marsupial Mouth Movements, former Indiana Poet Laureate George Kalamaras continues his ongoing series of Bone Sutras, poems that explore the interface of the human and natural world. Following his Surrealist forebears, Kalamaras explores the complexity of language, with startling images and juxtapositions, as a vehicle for visionary poetics. These poems seek to connect biological impulses to the realms of the spiritual and the discursive. In the process, the poems honor the varieties of human and animal life-mammals, marsupials, and the insect world, even probing the intelligence and vision that lie at the heart of molecules.
