Still keeping to the military aspects of the subject--at the commencement of the fourteenth century there was at the west end of St. Paul's Cathedral a waste piece of ground, which was the property of the City; and here it was the custom for the citizens to make a muster of arms under the command or inspection of the lord of Baynard Castle for the defence of the City, "so often as the said citizens might see fit." Moreover, at the east end of the church lay a smaller plot, on which the citizens held folkmotes and made parade of arms for preserving the King's peace. This was perhaps a relic of the Anglo-Saxon institution of Inward, which is mentioned in Domesday, and was designed for the maintenance of order within the walls. Adjacent to this smaller plot was the clochier or campanile of St. Paul's, which was a distinct building from the cathedral proper, and contained the great bell, known as the _motbelle_, by which the citizens were summoned to the Folkmote or an assembly of arms on occasions "when within the respective bailiwicks of the Aldermen anything unexpected, doubtful, or disastrous against the realm, or the royal crown, chanced suddenly to take place." When the King required the services of the Host of London against foreign enemies or outside the confines of the City, it is natural to suppose that the muster was held on the larger of the two spaces. The musters and parades of the Host probably lapsed when, by the sale of Baynard Castle, the Fitzwalters ceased to be _de facto_ Castellans of London. This is a fair inference from the circumstance that in 1321 the citizens complained before the Justiciars Itinerant that the Dean and Chapter had unlawfully taken possession of the vacant spaces, enclosed them with walls, and even erected dwelling-houses on the eastern plot. The blazonry of the Banner of St. Paul, which would have been no longer used, was so far forgotten that eighty or a hundred years later nothing remained but the sword, which was supposed to stand for the dagger of that militant mayor, Sir William Walworth, who is said to have terminated therewith the lawlessness of Wat Tyler. URBAN CHAPTER XV GOD'S PENNY Were we obliged to sum up the difference between town and country in one word, that word would be "trade." In mediaeval, far more than in modern, times country places had their fairs, but London, with its markets open Sundays and week-days, enjoyed all the benefits of a perpetual fair; from which strangers and foreigners, though under some disadvantages compared with freemen, were by no means excluded.
