A third-century scholar built a six-column Bible by hand
Around 235–245 CE, the Alexandrian scholar Origen laid out the Old Testament in six parallel columns — the Hebrew text, that same text spelled in Greek letters, and four different Greek translations side by side — so readers could compare them line for line. The result, called the Hexapla, was so enormous, by some estimates several thousand pages across dozens of volumes, that it was likely never fully copied; the original was eventually lost.
How we know
Origen c.184–253 CE; the Hexapla compiled c.235–245 CE at Caesarea, in six columns (Hebrew; Hebrew in Greek letters; and the Greek versions of Aquila, Symmachus, the Septuagint, and Theodotion). Estimated at thousands of pages; probably never copied in full; the original was lost.
