the Citizens shut their shops and hastened down to the Bridge in great multitudes; and a conflict would speedily have commenced, had it not been for the prudence and mediation of the Lord Mayor and Aldermen, Henry Chicheley, Archbishop of Canterbury, and the Prince of Portugal; who rode between the Protector and the Bishop, eight several times, ere they could bring them to any agreement; until, at length, they both consented to refer their dispute to the decision of John Plantagenet, Duke of Bedford, and Regent of France. The quarrel was, however, not concluded until the following Easter, which began on the last day of March. In defending London Bridge, the Protector appeared to be only retaliating upon the Bishop; for, in the third article of his charges against him, he stated, that once, when he was quietly riding to attend the King, the Bishop attempted his death at the Bridge foot, by assembling archers and soldiers in Southwark; by setting up engines to stop his way; by drawing the chain, used in ancient fortifications, across the Bridge; and by placing men in windows and turrets to cast down stones upon the heads of him and his followers. “I have already mentioned to you, that there were several Towers erected on London Bridge, both for defence and ornament; although we have not any authentic historical notice concerning them, until we arrive at the year 1426, when Stow tells us in his ‘_Survey_,’ volume i., pages 61, 65, that the Tower at the North end of the Drawbridge, over which the heads of Traitors were wont to be set, was then began to be newly built, in the Mayoralty of Sir John Raynewell, Citizen and Fishmonger; who bore for his Arms, Parted per pale indented Argent and Sable, a Chevron Gules. He laid one of the first stones of the edifice, and the Bridge-Master, with John Arnold and John Higham, the Sheriffs, laid the others. Upon each of these four stones, the name IHESUS was engraven in fair Roman characters, and at the rebuilding of this Gate and Tower in April 1577, they were laid up as Memorials in the Bridge House. The Drawbridge over which it was erected, was, at this period, readily raised up or lowered, that ships might pass up the River to Queenhithe; which was, during the use of this convenience, a principal strand for their lading and unlading, as being in the centre and heart of the City.
