The text had at least three layers: under the early medieval Hebrew records, a late-antique liturgical poem and the unidentified Hexapla text of about the eighth century were seen: the vocalization of the Psalm 22 by Greek letters and fragments of translation: Aquila, Symmachus, Septuagint and Theodotion - in that order. Taylor suggested that initially the text on the sheet was rewritten in 40 lines (33 preserved), and on each of them the Greek equivalents of the corresponding Hebrew words were accurately placed. In 1994, R. Jenkins re-examined a fragment of the Hexapla sheet and confirmed that the original text was rewritten in 40 lines, assuming that the Hebrew text was not copied in a square letter in this manuscript. Even earlier - in 1896 - Giovanni Mercati announced the discovery of the hexaplaric text of the Psalter in the Greek palimpsest [approximately] from the 13th-14th century from the Ambrosian library. However, this fragment (44 pages) was published only in 1958 and included ten psalms. It turned out that according to the peculiarities of the minuscule handwriting the text could not have been rewritten before the 9th century, while in the original manuscript there were five variants of the text in parallel columns versus six in the fragment from the Cairo genizah. They are related by the order of the texts - Greek transliteration, Aquila, Symmachus, Septuagint and Theodotion; The Hebrew text was never a square letter in this manuscript. The manuscript was intended, apparently, for exegetical needs, and each version of the text of the Psalms was accompanied by patristic commentaries. Apparently, it was a very voluminous and expensive manuscript. According to E. Grafton and M. Williams, these fragments allow us to shed some light on some features of the original Hexapla. In particular, the text in the columns of both the Milan and Cairo fragments is a line in a line, so that one Greek word exactly corresponds to one Greek word. At the same time, according to Grafton and Williams, the Hexapla could not have been a single codex, but rather an entire library - a series of uniform codices of fixed volume and large format (the Cairo fragment allows us to judge this). Assuming that the Hexapla original was rewritten by an official of 40 lines per sheet, and each column had only one Hebrew and Greek word, the volume could reach 40 volumes of 800 pages (400 sheets) in each.
