I hadn't yet seen this announced here, and I thought it might be of interest to B-Greekers. Researchers in Germany have recently discovered a manuscript from the 12th century that they believe contains a large number of homilies on the Psalms from Origen of Alexandria. Alin Suciu and Roger Pearse have good summaries and comments: http://alinsuciu.com/ and http://www.roger-pearse.com/weblog/.
One of the most exciting parts of this is that the manuscript is viewable (and downloadable!) online for free. I've posted some transcription, translation, and commentary on a portion of the manuscript here:http://mapoulos.wordpress.com. I'd encourage you all to take a look, if you've an interest in Origen. Roger Pearse has posted directions to view it:
The manuscript has already been digitised by the Bavarian State Library and is already available to everyone on the internet:

If you've not read from a manuscript before, the process can be disorienting. I've posted a page here http://mapoulos.wordpress.com/a-short-tutorial-on-greek-paleography/ with a few tips.
