4 Esdras
4 Esdras is not in the LXX but the Vulgate calls it 4 Esdras and is not included in Medieval literature. According to wikipedia,
4 Ezra (2 Esdras 3–14): probably written in Hebrew by a Jew.
5 Ezra (2 Esdras 1–2): probably Latin by a Christian.
6 Ezra (2 Esdras 15–16): probably Greek by a Levantine Christian.
St. Ambrose of Milan cited it with special frequency. Such was its popularity that St. Jerome translated it as part of the Old Testament of the Vulgate, though he placed it in an appendix with other popular texts which he personally did not hold to be canonical. It was well known in the West in its Latin form until the time of the Protestant Reformation. Christopher Columbus cited 4 Ezra 6:2 as one of his proofs of the world’s composition in his appeal to the Catholic Monarchs for funding. It is likewise found in Ethiopian and Armenian Old Testaments, and importantly for the Orthodox Church, in the Georgian, through which the text found its way into the Slavonic Biblical tradition. It has been included in every approved Slavonic and Russian printed Bible. 4 Ezra is therefore a text at the fringe of the Old Testament tradition, either just in or just out depending upon the linguistic tradition of Orthodoxy in which one is located.
