Well, the ETC blog has been unusually quiet during SBL, though many of the bloggers have been attending. I think this may be because so many of them are participating in events while here.
There have been many tc-related events here, some of which clash with each other. However, I thought it would be worthwhile reporting on the 'unveiling' this morning by Hugh Houghton of his recent identification of 4 previously unnoticed Old Latin manuscripts of John's Gospel (or manuscripts which contain a mixture of Old Latin and Vulgate text). They had been overlooked as Old Latin witnesses previously because statistics from test passages placed them reasonably close to the Vulgate. However, this was due to 'block mixture', or the presence of different text profiles within the same manuscripts, which can arise due to the use of more than one exemplar in an ancestor. It sounds like a great discovery.
Update (TW): If I understood correctly, Hugh has added the new MSS to the online VL edition at www.iohannes.com so anyone can access the text and check it out.
