On the Theophania

Eusebius of Caesarea (ad 260/265-339/340), also known as Eusebius Pamphili, was a Greek 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 well learned Christian of his time. He wrote 'Demonstrations of the Gospel,' 'Preparations for the Gospel,' and 'On Discrepancies' between the Gospels, studies of the Biblical text. As "Father of Church History" he produced the 'Ecclesiastical History,' 'On the Life of Pamphilus,' the 'Chronicle' and 'On the Martyrs.'
