The British Museum has launched a guide focusing on elements of homosexuality to be found in its collection.

A Little Gay History draws on objects ranging from ancient Egyptian papyri and the erotic scenes on the Roman Warren Cup to images by David Hockney.

The guide is accompanied by an audio trail featuring Simon Russell Beale....
