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.
