In the first column was the contemporary Hebrew, in the second a Greek transliteration of it, then the newer Greek versions each in their own columns. Origen also kept a column for the Old Greek (the Septuagint) and next to it was a critical apparatus combining readings from all the Greek versions with editor's marks indicating to which version each stitch belonged. [2] Perhaps only three copies of the voluminous Hexapla were ever made, but Origen's combined text was copied, eventually without the editing marks, and the older uncombined text of the LXX was neglected. Thus this combined text became the first major Christian recension of the LXX, often called the Hexaplar rescension. In the centuries following Origen, two other major recensions were made by Lucian and Hesychius.
