This week saw the arrival in ITSEE of the print copy of the new volume of original research papers originating from the The Ninth Birmingham Colloquium on the Textual Criticism of the New Testament. We are very glad to add this to our increasing collection of home grown books! The colloquium brought together scholars from more than twelve countries in March 2015 and was held in association with the European Research Council-funded COMPAUL project which, based in ITSEE, has been examining commentaries on the Pauline Epistles as sources for the early history of the biblical text since 2011. The volume of papers resulting from the colloquium therefore has a particular emphasis on exploring the composition, transmission and significance of commentary writings and includes several papers by members of the COMPAUL project. Research Fellows, Dr Rosalind MacLachlan and Dr Susan B. Griffith, talk about non-biblical commentaries in the Early Christian period and Ambrose's commentary on Luke, respectively, while, Dr Dr Christina Kreinecker, who was a Research Fellow on the project from 2011-2013, discusses Rufinus' translation of Origen's Commentary on Romans. In addition COMPAUL's PhD student, Theodaora Panella, presents some of her fruitful research in to Pauline catenae. The volume begins with a general introduction to Greek New Testament catenae and commentaries by Professor David Parker and Dr Hugh Houghton, Principle Investigator of the COMPAUL Project. Other papers in the collection deal with the layout and sources of commentary manuscripts and the work of principal Greek and Latin commentators, plus papers on commentary and catena manuscripts in other biblical languages and traditions.
