According to Papias, a young disciple of the apostle John, claimed that John Mark, wrote down what Peter told to him for the book of Mark. And that Matthew himself wrote Matthew.
"And in his own writing he Papias also hands down other accounts of the aforementioned Aristion of the words of the Lord and the traditions of the presbyter John, to which we refer those truly interested. Of necessity, we will now add to his reports set forth above a tradition about Mark who wrote the gospel, which he set forth as follows:
And the presbyter would say this: Mark, who had indeed been Peter's interpreter, accurately wrote as much as he remembered, yet not in order, about that which was either said or did by the Lord. For he neither heard the Lord nor followed him, but later, as I said, Peter, who would make the teachings anecdotally but not exactly an arrangement of the Lord's reports, so that Mark did not fail by writing certain things as he recalled. For he had one purpose, not to omit what he heard or falsify them.
Now this is reported by Papias about Mark, but about Matthew this was said, Now Matthew compiled the reports in a Hebrew manner of speech, but each interpreted them as he could."
