The essays collected in this volume examine manifestations of our sublime cosmos in ancient literature and its reception. Individual themes include religious mystery; calendrical and cyclical thinking as ordering principles of human experience; divine birth and the manifold nature of divinity (both awesome and terrifying); contemplation of the sky and meteorological (ir)regularity; fears associated with overpowering natural and anthropogenic events; and the aspirations and limitations of human expression. In texts ranging from Homer to Keats, the volume's chapters apply diverse critical methods and approaches that engage with sublimity in various aesthetic, agential and metaphysical aspects. The ancient texts - epic, dramatic, historiographic and lyric - treated here are rooted in a remote world where, within a framework of (perceived) celestial order, literature, myth and science still communicated profoundly, a tradition that continued in literary receptions of these ancient works. This volume honours the intellectual legacy of Thomas D. Worthen, a scholar whose expertise and insights cut across multiple disciplines, and who influenced and inspired students and colleagues at the University of Arizona, USA, for over three decades. Beyond clarifying temporally and culturally distant contemplations of the human universe, these essays aim to inform the continuing sense of wonder and horror at the sublime heights and depths of our ever-changing cosmos. This is an excellent study of the idea of the sublime cosmos in ancient Greco-Roman thought: wide ranging, informative, up to date, methodologically diverse and dealing with interesting intersections of myth, history and science.
