Eusebius of Caesarea, ca. 260-340 CE, born in Palestine, was a student of the presbyter Pamphilus whom he loyally supported during Diocletian's persecution. He was himself imprisoned in Egypt, but became Bishop of Caesarea about 314. At the Council of Nicaea in 325 he sat by the emperor, led a party of moderates, and made the first draft of the famous creed.

Of Eusebius's many learned publications we have "Martyrs of Palestine" and "Life of Constantine;" several apologetic and polemic works; parts of his commentaries on the Psalms and Isaiah; and the Chronographia, known chiefly in Armenian and Syriac versions of the original Greek. But Eusebius's chief fame rests on the "History of the Christian Church" in ten books published in 324-325, the most important ecclesiastical history of ancient times, a great treasury of knowledge about the early Church.

This volume in the Library of Christian Classics series offers fresh translations of selected works of Clement and Origen of Alexandria.

Long recognized for the quality of its translations, introductions, explanatory notes, and indexes, the Library of Christian Classics provides scholars and students with modern English translations of some of the most significant Christian theological texts in history. Through these works--each written prior to the end of the sixteenth century--contemporary readers are able to engage the ideas that have shaped Christian theology and the church through the centuries.
