Papias, according to Eusebius
Ch 3.39.11. The same writer gives also other accounts which he says came to him through unwritten tradition, certain strange parables and teachings of the Saviour, and some other more mythical things. 12. To these belong his statement that there will be a period of some thousand years after the resurrection of the dead, and that the kingdom of Christ will be set up in material form on this very earth. I suppose he got these ideas through a misunderstanding of the apostolic accounts, not perceiving that the things said by them were spoken mystically in figures.
