Papias of Hierapolis (c. 70-155) Little is known about Papias. He is, however, one of our most important witnesses for the origins of the canonical gospels. According Eusebius, Papias wrote this:

"Mark having become the interpreter of Peter, wrote down accurately whatsoever he remembered. It was not, however, in exact order that he related the sayings or deeds of Christ. For he neither heard the Lord nor accompanied Him. But afterwards, as I said, he accompanied Peter, who accommodated his instructions to the necessities [of his hearers], but with no intention of giving a regular narrative of the Lord's sayings. Wherefore Mark made no mistake in thus writing some things as he remembered them. For of one thing he took especial care, not to omit anything he had heard, and not to put anything fictitious into the statements. Matthew put together the oracles [of the Lord] in the Hebrew language, and each one interpreted them as best he could."

Papias is reckoned among the apostolic fathers although his writings survive only in citations by later authors as above. He is only known to have written five books, called the Exegesis of the Oracles of the Lord.

Papias was a contemporary of Ignatius and Polycarp and, according to Irenaeus, a hearer of the Apostle John.
