Melito of Sardis d. c. 180 ADExtracts, preserved in Eusebius, Church History 4.26.13–14
So I went to the East, to the place where these things were preached and done. When I had learned exactly the books of the Old Covenant, I set them down and send them to you. Their names are these. Five of Moses: Genesis, Exodus, Numbers, Leviticus, Deuteronomy. Joshua son of Nun, Judges, Ruth. Four of Kingdoms, two of Chronicles. The Psalms of David. Solomon's Proverbs, which is also called Wisdom, Ecclesiastes, the Song of Songs, Job. The prophets: Isaiah, Jeremiah, the Twelve in one book, Daniel, Ezekiel. Ezra.
The oldest Christian list of Old Testament books. Melito travelled to Palestine to find out which books the Jews used. Esther is missing. "Wisdom" here is a second name for Proverbs, not the Wisdom of Solomon.
