Papias of Hierapolis, writing around 130 and quoted by Eusebius, says the elder used to say this: Mark, having become Peter's interpreter, wrote accurately as many things as he remembered, though not in order, of the things said and done by the Lord — for he had neither heard the Lord nor followed him, but afterwards followed Peter, who adapted his teaching to the need without making an ordered account of the Lord's sayings. It is a strange thing to invent. It concedes that the gospel is second-hand and out of order, and defends it anyway, which is not how a claim of authority is usually constructed — and it is the earliest external statement about the writing of any gospel.
To set down what Peter preached, at the request of those who heard it.
The second gospel, and the earliest account anyone gives of how a gospel was made.
