This lecture by Dr Sally Dormer of the Victoria and Albert Museum is absolutely fascinating. It is a bit of a commitment, being over an hour long, but try to see it. You’ll learn a lot — well, at least I did.

The lecture is part of the Gresham College series of lectures. Gresham College in the City of London has been giving free public lectures for 400 years. There’s a life-time’s study here: click on the Lectures and Events tab.
