Facsimile edition of the "Patrologia Graeca", edited by Jacques-Paul Migne from 1857 to 1866 in more than 160 volumes. The database comprises works of the Greek church literature beginning with Pseudo-Clemens (100 AD) up to Kallistos (1478) and thus makes available the important Greek Christian authors and the most influential works of theology, philosophy, history and literature of the late ancient world and the early Middle Ages. Texts are made easily accessible by an index of contents in Latin and Greek language, by an index of authors, a title index and an index of subject. All of these indexes are full text ones.
