Coat of arms of the City of London 13th-century seal, and on two embroidered seal-bags of 1319, that depicted St Paul holding a sword. It is sometimes said that the sword in the 1381 arms represents the dagger used by Lord Mayor of London William Walworth to kill Wat Tyler, leader of the Peasants' Revolt, on 15 June 1381. This tradition dates at least as far back as the first edition of "Holinshed's Chronicles", published in 1577, but cannot be correct, as the arms were in use some months before Tyler's death. The crest and supporters came into use in the 17th century, but were used without authority
Frederick Bull (Lord Mayor of London) 1772. He became Lord Mayor of London for 1773-74. Bull stood for the City of London at a by-election in 1773 and was returned after a hard-fought contest on 23 December 1773. He was returned for the City after a contest again in 1774 and 1780. Bull was a Dissenter and close supporter of John Wilkes. He followed the Bill of Rights Society programme throughout his parliamentary career. His politics were radical and anti-Popery and in the spring of 1780 he supported Lord George Gordon’s Protestant crusade which led to the riots in June. Bull retired from business about 1782.
