Portrait of a dead child

I came across this in the Radio Times, in an article about ceramics for the Handmade in Britain series that starts next week (9pm on 10 October, BBC Four). It's a portrait of Lydia Dwight by her father John, made in 1674 in his Fulham pottery. It's in the V & A. I must look for it the next time I'm there. It's beautiful and sad.
