Literature. — Patristics began with the work of Jerome (d. 419), De viris illustribus s. de scriptoribus ecclesiasticis, which contains biographical sketches of the most eminent Christian authors down to the 5th century. It was continued by Gennadius (490), Isidore of Spain, and other mediaeval writers. Since the Reformation this study was especially cultivated by Roman Catholic scholars, as Bellarmine, Oudin, Du Pin, C. Nourry, Tillemont, Ceillier, Lumper, Sprenger, Mohler, Fessler, Alzog; and by some Anglican divines, as Cave, Pearson, Fell, and the Tractarian school. The Germans have cultivated the biographical and critical department, and furnished a number of valuable patristic monographs, as Tertullian and Chrysostom by Neander, Origen by Thomasius and Redepenning, Gregory of Nazianzum by Ullmann, Jerome by Zochler, Augustine by Bindemann. The best editions of the fathers are the Benedictine, as far as they go, and the most complete and convenient (though by no means the most critical) is Migne's Patrologice Cursus completus s. Bibliotheca Universalis... omnium SS. Patrum, Doctorum, Scriptorumque ecclesiasticorum, embracing the ecclesiastical literature from the apostolic fathers down to the age of Innocent III (Paris, 1844 sq.). A more critical edition of the Latin fathers was begun under the auspices of the Academy of Vienna (1866), and embraces so far Sulpicius Severus, Minucius Felix, and Cyprian. Of modern works on patristics, the principal are: Mohler, Patrologie (ed. Reithmayr, Regensburg, 1850, only 1 vol. to close of 300); Fessler, Institutiones Patrol. (Oenip. 1850, 2 vols., to Grengory the Great); Alzog, Grundriss der Patrologie (2d ed. Freiburg, 1869; 3d ed. 1876); Donaldson, A Critical History of Christian Literature and Doctrine from the Death of the Apostles to the Nicene Council (Lond. 1864-66, 3 vols.). A biographical Dictionary of the first ten centuries, under the editorship of William Smith, has been published in London as a sequel to the Dictionary of Christian Antiquities, of which the first volume was issued in 1875.
