Times Jumbo 1010 (8 Dec 2012)

Solving time: About 1 hour 40 minutes.

On the whole a pleasant solve. I was held up by never having heard of either of the two long ones at 4 & 15. I loved the 'four out of five' device at 10d so I'll give that my COD.

51	S(TO)IC means a philosopher in its original sense. The adjective came later. I'm not sure about TO for 'closed' though. I would argue that if a door is to, then it is ajar, and hence NOT closed. But maybe there's another meaning which I'm overlooking.
53	ROUE + Norman
