The Patrologia Graeca is an edited collection of writings by the Church Fathers and various secular writers, in the Greek language.
An important final volume, which included some supplements and a full index, was never published, as the plates were destroyed in a fire (1868) at the printer.
In 1912, Garnier Frères, Paris, published a Patrologia Graeca index volume, edited by Ferdinand Cavallera.
As with the Patrologia Latina, the authors are (with a few exceptions) in chronological order, spanning the period from the earliest Christian writers to the Fall of Constantinople.
It comprises additional supplements: introductions, bibliographies, biographical summaries, detailed tables of contents and hagiographic passages.
