Presently I'm in Lampeter doing a two week summer school course I mentioned a while back. It is hard work but very rewarding to be able to devote some time to the subject and make real progress. I doubt my greek will ever be up to reading Ptolemy but I do one day hope to be able to use it for New Testament studies and looking at science in the Byzantine Empire.
