Patrologiæ Græcæ is an electronic version of Jacques-Paul Migne's The Patrologiae Cursus Completus, Series Graeca, originally published between 1857 and 1866. It contains more than 160 volumes of Greek material (with Latin translations) relevant to the study of the history of the Christian Church from its beginnings through the Council of Florence in 1439. It includes the writings of the church leaders who wrote in Greek, including both the Eastern "Fathers" and Western Christians who wrote before the Latin takeover of the West in the third century.
Highlights include the early writings collectively known as the Apostolic Fathers (such as the Epistles of Clement and The Shepherd of Hermas), the church historian Eusebius, the controversial theologian Origen, and the Cappadocian Fathers: Basil the Great, Gregory of Nazianzus, and Gregory of Nyssa.
