What it is
The Old Testament laid out in six parallel columns — Hebrew, Hebrew in Greek letters, and four Greek versions — with marks showing where the Septuagint added to or omitted from the Hebrew.
Why it lasted
The first work of textual criticism in Christian history, and a scholarly undertaking on a scale not attempted again for a thousand years.
Where to read it
This work is in the public domain and can be read in full, free, at the archives below. The Library catalogues it; it does not host the text.
These open a search on each archive rather than a direct link, which is the honest way to point at an edition nobody here has checked line by line.
