This book provides an ecocritical analysis of the poetry of the famous Nigerian poet Niyi Osundare. It interrogates the intricate interface between time and nature in 11 of Osundare?s defining poetry collections. This is a book of postcolonial ecocriticism from an African perspective. It brings together the ecocritical theory of animism and theories of geologic time in the discussion of Osundare?s poetry. Osundare shows that animism has a lot to offer in enriching human understanding of the ecosystem. And while he eloquently catalogues problems undermining the health of the earth in this age of the Anthropocene and the Capitalocene in his poetry, he also holds on to the hope of a better future. The book concludes that Osundare?s optimism is what informs his use of poetry to press humankind to rise to the duty of salvaging the environment. Deploying an interdisciplinary approach that stretches across the fields of literature, religion, geology, physics, economics, and anthropology, this book will be an important read for those looking for fresh ways to understand Osundare?s poetry and African nature writing.
