The Gorgias Encyclopedic Dictionary of the Syriac Heritage (GEDSH) is the first major encyclopedia-type reference work devoted exclusively to Syriac Christianity, both as a field of scholarly inquiry and as the inheritance of Syriac Christians today. In more than 600 entries it covers the Syriac heritage from its beginnings in the first centuries of the Common Era up to the present day. Special attention is given to authors, literary works, scholars, and locations that are associated with the Classical Syriac tradition. Within this tradition, the diversity of Syriac Christianity is highlighted as well as Syriac Christianity's broader literary and historical contexts, with major entries devoted to Greek and Arabic authors and more general themes, such as Syriac Christianity's contacts with Judaism and Islam, and with Armenian, Coptic, Ethiopian, and Georgian Christianities.

Aristotle's voluminous writings on animals have often been marginalised in the history of philosophy. Providing the first full-length comprehensive account of Aristotle's biology, its background, content and influence, this Companion situates his study of living nature within his broader philosophy and theology and differentiates it from other medical and philosophical theories. An overview of empiricism in Aristotle's Historia Animalium is followed by an account of the general methodology recommended in the Parts of Animals. An account of the importance of Aristotle's teleological perspective and the fundamental metaphysics of biological entities provides a basis for understanding living capacities, such as nutrition, reproduction, perception and self-motion, in his philosophy. The importance of Aristotle's zoology to both his ethics and political philosophy is highlighted. The volume explores in detail the changing interpretations and influences of Aristotle's biological works from antiquity to modern philosophy of science. It is essential for both students and scholars.
