This third volume covers the eventful period of Christian emperors, patriarchs, and oecumenical councils, from Constantine the Great to Gregory the Great. It completes the history of Ancient Christianity, which is the common inheritance of Greek, Latin, and Evangelical Christendom. It will be followed at no distant time by the History of Mediaeval Christianity to the Reformation. -The Author, New York, January, 1884

This voluminous work on Church History by Philip Schaff (1819-1893) was originally published between 1858 and 1893 in eight volumes in the USA and covers the period from the beginnings of Biblical Christianity in A.D. 1 to the History of the Reformation in Germany and Switzerland (1517-1648). Being still a popular text in North America, this work had been out of print for over a century and has now been carefully edited and reformatted for republication in three volumes, each of them containing the text of two volumes of the original edition. Schaff’s work, unlike other works in the field, covers a multitude of church history-related aspects – from church doctrine, policy, events and processes to aspects of social moral and family life, arts and more. It is a very comprehensive text, extremely well-written and readable, rich in material and sources used, and attests to the excellence of protestant German theological scholarship under the influence of emerging Historical-Critical Biblical Exegesis at his time. This second volume covers the period from the Nicene and Post-Nicene Fathers to Medieval Christianity (A. D. 311-1073).

Science is a living, organic activity, the meaning and understanding of which have evolved incrementally over human history. This book, the second in a roughly chronological series, explores the evolution of science from the advents of Christianity and Islam through the Middle Ages, focusing especially on the historical relationship between science and religion. Specific topics include technological innovations during the Middle Ages; Islamic science; the Crusades; Gothic cathedrals; and the founding of Western universities. Close attention is given to such figures as Paul the Apostle, Hippolytus, Lactantius, Cyril of Alexandria, Hypatia, Cosmas Indicopleustes, and the Prophet Mohammed.
