There is but one CFP today, so I’ve had to pad this a bit with other potentially interesting things.
Universitas scholarium. The social and cultural history of the European student from the Middle Ages to the Present
And a few errata which are not CFPs, but may be of some interest anyway:
Footsteps of King Arthur
19 April 2013, 10am-5pm
A one-day symposium at Glastonbury Abbey featuring some excellent researchers (if I can arrange to get and stay there, I will totally go.)
st Catherine’s University Latin Summer Institute
3 June 13-9 Aug 13, Minneapolis, MN
Keele University Latin Summer School
Much closer and cheaper if you’re in the UK than Minnesota.
27 July-1 Aug 2013
There are, of course, more Latin summer schools on a variety of continents out there; these are just the two that have popped up in my inbox recently. Durham generally has a good one in the UK, as does Notre Dame in the US.
