Another TV job today, this time with a bit of filming (in the rain) of something I am sworn to secrecy about – in fact if the crew’s hotel printer had been working, I would have signed up to silence as well. I’ll let you know when the programme is to be broadcast (I’m a consultant to the project), but it’s likely to be some time yet. In the meantime here is a photo of some garden grapes (looking like our biggest fruiting yet, they must like the rain). And of Bruce Bradley, a skilled flint knapper at Exeter University, whose work like that of all good experimental knappers is so important and so under-appreciated for its contribution to our understanding of past cultures and the evolution of human intelligence. None of which has anything to do with the film.
