Eusebius was a Christian historian and bishop of Caesarea who flourished early in century III. His literary works are invaluable to the study of the Christianity of the first three centuries.

Photius of Constantinople summarizes a few Eusebian works in his Bibliotheca. Chapters 9-13, 27, 39, 118, and 127 all describe books by Eusebius, and chapter 89 deals with the continuation of the Church History by Gelasius of Caesarea.

Jerome, On Famous Men 81:

Eusebius, Caesareae Palaestinae episcopus in scripturis divinis studiosissimus, et bibliothecae divinae, cum Pamphilo martyre, diligentissimus pervestigator, edidit infinita volumina. de quibus haec sunt: ευαγγελικης αποδειξεως libri viginti, ευαγγελικης προπαρασκευης libri quindecim, θεοφανειας libri quinque, ecclesiasticae historiae libri decem, chronicorum canonum omnimoda historia, et eorum επιτομη, et de evangeliorum diaphonia, in Isaiam libri decem, et contra Porphyrium, qui eodem tempore scribebat in Sicilia, ut quidam putant, libri triginta, de quibus ad me viginti tantum pervenerunt; τοπικων liber unus, απολογιας pro Origene libri sex, de vita Pamphili libri tres, de martyribus alia opuscula, et in centum quinquaginta psalmos eruditissimi commentarii, et multa alia. floruit maxime sub Constantino imperatore et Constantio, et ob amicitiam Pamphili martyris, ab eo cognomentum sortitus est.

Eusebius bishop of Caesarea in Palestine was diligent in the study of divine scriptures and with Pamphilus the martyr a most diligent investigator of the divine library. He published a great number of volumes among which are the following: Demonstration of the gospel in twenty books, preparation for the gospel in fifteen books, theophany in five books, church history in ten books, chronicle of universal history and an epitome of this last; also On discrepancies between the gospels, on Isaiah in ten books, also against Porphyry, who was writing at that same time in Sicily, as some think, in twenty-five books, also one book of topics, six books of apology for Origen, three books on the life of Pamphilus, other brief works On the martyrs, exceedingly learned commentaries on one hundred and fifty psalms, and many others. He flourished chiefly in the reigns of Constantine the Great and Constantius. His surname Pamphilus arose from his friendship for Pamphilus the martyr.
