"Bread of heaven, bread of heaven ..." Down at the corner where St Paul's Churchyard joins Fleet Street, a crowd has gathered. Around the steps of the cathedral, the Occupy protest sprawls, its hundred or so tents arranged in rows, making tiny streets in the expansive paved yard. Above the one and two-person many-coloured pods rise the larger units -- the info tent, the media and food tent, and the largest of them all, like an old meeting hall, the "Tent City University" tent.

"Occupy London" has become a village within a city. Gathered thus around the cathedral, it has an early medieval air, but considered of itself it reaches back much further, to the settlements that predate Londinium, the city founded by the Romans to impose imperial order.
