I was prompted by the very good recent book on Hawksmoor – Terror and Magnificence: The London Churches of Nicholas Hawksmoor by David Meara, a retired archdeacon – to stop and have a look at the carvings on the small circular bollards which protect the St. Alfege from the adjacent road. 

The carvings are, of course, very worn – three hundred years of weather and exhaust – but are fine.  Hawksmoor ?  Or the free invention of stone carvers who look as if they have worked on St. Paul’s:-
