Church History of Eusebius: ALL 10 Books in One Volume 
The Early Christianity: From A.D. 1-324

The Church History of Eusebius, the bishop of Caesarea, was a 4th-century pioneer work giving a chronological account of the development of Early Christianity from the 1st century to the 4th century. It was written in Koine Greek, and survives also in Latin, Syriac and Armenian manuscripts. Eusebius had access to the Theological Library of Caesarea and made use of many ecclesiastical monuments and documents, acts of the martyrs, letters, extracts from earlier Christian writings, lists of bishops, and similar sources, often quoting the originals at great length so that his work contains materials not elsewhere preserved. The result was the first full-length historical narrative written from a Christian point of view.

عن المؤلف

Eusebius of Caesarea (AD 260/265 – 339/340) was a historian of Christianity, exegete, and Christian polemicist. He became the bishop of Caesarea Maritima about 314 AD. Together with Pamphilus, he was a scholar of the Biblical canon and is regarded as an extremely learned Christian of his time. As ‘Father of Church History’ he produced the Ecclesiastical History, On the Life of Pamphilus, and the Chronicle and On the Martyrs. In his Church History or Ecclesiastical History, Eusebius wrote the first surviving history of the Christian Church as a chronologically-ordered account, based on earlier sources, complete from the period of the Apostles to his own epoch.
