C. E. Hammond's Antient Liturgies provided a valuable resource at an early stage in comparative liturgical studies. Free of extensive critical apparatus, Antient Liturgies presents a collection of historic forms of worship from the Western, Eastern, and Oriental Churches. This extract from the book focuses on the Liturgy of Constantinople. As Hammond explains, this liturgy contains elements of the St. Basil, St. Chrysostom, and Presanctified liturgies presented in Greek. As an analytical introduction this early study continues to provide a broad overview of early Christian worship made available in an accessible and convenient format for students and scholars.
