Melito provides what is possibly the earliest known Christian canon of what he termed the "Old Testament", having traveled to Palestine (probably to the library at Caesarea Maritima) seeking to acquire accurate information about which books should be accepted as canonical.
Other candidates for earliest Christian canon include the Bryennios List and the Muratorian fragment.
Melito's canon is found in Eusebius EH4.26.13–14:[1] Accordingly when I went East and came to the place where these things were preached and done, I learned accurately the books of the Old Testament, and send them to thee as written below.
Their names are as follows: Of Moses, five books: Genesis, Exodus, Numbers, Leviticus, Deuteronomy; Jesus Nave, Judges, Ruth; of Kings, four books;[2] of Chronicles, two; the Psalms of David, the Proverbs of Solomon, Wisdom also, Ecclesiastes, Song of Songs, Job; of Prophets, Isaiah, Jeremiah; of the twelve prophets, one book ; Daniel, Ezekiel, Esdras.
From which also I have made the extracts, dividing them into six books.Melito's list almost fully corresponds to the Jewish Tanakh and Protestant canon.
