The Book of Sirach (Latin: Ecclesiasticus) is a beautiful wisdom work that blends Greek and Hebrew thought. It’s the last of the Old Testament books composed, and was probably written only two centuries before the first of the New Testament texts, providing an important glimpse into the development of faith and philosophy between the OT world and the NT world.
The last century has seen the recovery of various important manuscripts of Sirach, first from them middle ages, and then later, fragments from Qumran. These manuscripts are scattered in collections in Cambridge, Oxford, London, Paris, New York, Los Angeles, and Jerusalem, making close examination and comparison of text a difficult thing. A new project called The Book of Ben Sirah is making that job much easier by attempting to unite all extant manuscripts into a single site. (Only the pages at the Bodleian Library are not included for rights reasons, but the site includes links to them.)
Right now, there are just hi-res scans up, but transcriptions, translations, and resources will be added now that the project is live. Check out the link to get a glimpse of these important manuscripts.
