This volume presents a survey of what Arabic philosophers, as commentators of Aristotle's Physics, have contributed to philosophy and science in the Middle Ages. It investigates to what extent they influenced one another and to what extent they were influenced by previous Greek commentators. Besides Ibn Bajja's Commentary on the Physics, which had up to now only partially been edited, the commentaries of Ibn as-Samh, Abu Bisr Matta, Abul-Faraj ibn at-tayyib and Ibn Rusd are surveyed and discussed. The book also contains an account of an Arabic paraphrase of Philoponus' commentary on the Physics, which is of special interest because this commentary was partly lost. A special feature of the book is the edition of the unpublished parts of Ibn Bajja's commentary.
