The volume contains highly original articles on Islamic history, law, and thought, each either proposing new hypotheses or readjusting existing ones. The contributions range from studies in the formulation of the pre-Islamic Arabian calendar to notes on the "blood-money group" in Islamic law, and to transformations in Arabic logic in the post-Avicennan period. Prepared by former students of Michael A. Cook, to whom this volume is dedicated, these studies not only shed new light on the development of the Islamic scholarly tradition from various perspectives, but together they also represent the honoree's vast, profound, and continuing impact on the field. This collection of highly empirical articles is intended for scholars and students specializing in various subfields within Islamic Studies.
