Which six texts were placed in parallel columns in Origen’s Hexapla?

The Hexapla, compiled by the theologian Origen, presented six versions of the Old Testament in parallel columns to facilitate comparison. The six texts included were:12

• The Hebrew text12
• The Hebrew text transliterated into Greek characters12
• The Greek version of Aquila12
• The Greek version of Symmachus12
• The [Septuagint]12
• The Greek version of [Theodotion]2

While these six columns formed the core of the work, Origen occasionally included additional columns for certain books, such as the Psalms, which featured three extra Greek texts from unknown sources.12
