Athanasius of Alexandria (about 300-373) commented on the book of Psalms, as Jerome stated in 393. This exegesis has not been preserved directly, but it appeared from the sixth century in the Greek catena, and in an unusual form. The commentary, which includes all the Psalms, is divided into 22 centuries, each century being a series of hundred passages. In all there are 2,161 passages, numbered with great precision in a 10th century Constantinopolitan manuscript, the Vaticanus Gracus 754. This division (...) can be dated back to the sixth century, because the text in this form is confirmed by four oriental versions and by a Byzantine anthology from the end of the 11th century. (shrink)
