PART I.
The Reason of the Title. An Account of those Authors that have written upon the same Subject. A general View of the Design of this Work.
THE Name of Bibliotheca, or Library, is not only given to those Places that contain great Numbers of Books; but also to Collections that have been made by several Authors, and to those Books that treat of their Works. Thus Collections of the Works of several Fathers, are called Bibliothecae Patrum: A General History drawn out of vast Numbers of Historians, such as Diodorus Siculus's Bibliotheca Historica: A Book that treats of the Sacred Volumes of Scripture, such as Sixtus Senensis's Bibliotheca Sancta; or rather, Bibliocheca Sacrorum Codicum: A Treatise upon those Authors who have written concerning Matters of Religion, as this of ours is, Bibliotheca Authorum Ecclesiasticorum: And, in short, any Book that speaks indifferently of all sorts of Authors, and Writings, composed upon different Occasions, may be called a Bibliotheca.
This is not the first time that such sort of Libraries have been made: Apollodorus, an Athenian, a most learned Grammarian, that lived under the Reign of Ptolomaeus Euergetes, Two Hundred and Forty Years, or thereabouts, before the Nativity of Jesus Christ, com∣posed a Bibliotheca of the Original of the Gods; that is to say, of the most ancient History, as it lies disguised under Fictions and Fables. In imitation of him, Diodorus Siculus, that lived in Augustus's Time, composed a Bibliotheca of General History; which was taken out of an infinite Number of Authors. To these, we must join those Authors that have written the Lives of Illustrious Persons; such as Hermippus, Antigonus, Satyrus, Heraclides, Aristoxe∣nus, and Diogenes Laertius, amongst the Greeks; and amongst the Latins, Varro, Tully, Ne∣pos, Santra, Hyginus, and Suetonius; who have composed the Lives of the Philosophers, and other Authors.
To descend now to those Christians that have made Catalogues of their own Authors: Are not Clemens Alexandrinus's Stromata a Bibliotheca of the Opinions and Judgments of an incredible Number of Writers? May not the History of Eusebius be called a Library of Ec∣clesiastical Authors? since his whole Book is little else but an Account of their Lives, a Ca∣talogue of their Works, and a Collection of several memorable Passages. But St. Jerom is the first of the Christians, that has expresly treated of Ecclesiastical Authors; which Book was translated into Greek by Sophronius. Gennadius of Marseilles, Isidore of Sevil, Ildefon∣sus of Toledo, continued it down to their own Times. Honorius Bishop of Autun made a small Abridgment of these four Authors. Sigebert of Gemblours, and Henry of Ghent, con∣tinued their Books down to St. Bernard's Time. And Lastly, Auberius Miraeus, who pub∣lished these Authors under the Title of Bibliotheca Ecclesiastica, continued the History of these Ecclesiastical Writers down to our Times. Trithemius, who lived about Two Hun∣dred Years ago, made a distinct Book upon the same Subject. We ought not to forget the Roman Council, held under Pope Gelasius the First, in the Year 494, in which there is a
