The '''''Patrologia Graeca''''' (also ''Patrologiæ Græcæ'' or ''Patrologiae Cursus Completus, Series Graeca'') is an edited collection of writings by the [[Church Fathers]] and various secular writers, in [[Koine Greek]], or medieval variants of the language. It consists of 161 volumes produced in 1857–1866 by J. P. Migne's ''Imprimerie Catholique''. It includes both the Eastern Fathers and those Western authors who wrote before Latin became predominant in the West in the 3rd century, e.g., the early writings collectively known as the [[Apostolic Fathers]], such as the ''[[First Epistle of Clement|Epistles of Clement]]'' and the ''[[Shepherd of Hermas]]'', [[Eusebius of Caesarea|Eusebius]], [[Origen]], and the [[Cappadocian Fathers]] [[Basil the Great]], [[Gregory of Nazianzus]], and [[Gregory of Nyssa]].
