An important Act passed in 1364 obliged all artificers and people of mysteries to choose each his own mystery, and, having so chosen it, to use no other. At the close of Edward the Third's reign, in 1376, a further ordinance was made, as we have seen, by the City Commonalty, transferring the right to elect all City dignitaries and officers, including members of Parliament, from the ward representatives to the members of the Trade Guilds. The right of electing members of the Common Council was soon restored to the inhabitants of the wards, but the election of the Lord Mayor, Sheriffs, Chamberlain, and other officers has continued in the hands of the livery down to the present day, a privilege unique in the history of the country. From an early period certain of the chief Companies have been separated from the remaining Guilds, and known as the Twelve Great Companies, the rest of the Companies following after them in an acknowledged precedence. The Twelve Companies were distinguished by their greater wealth, and the Lord Mayor was obliged as a necessary qualification for office to be a member of one of these Guilds. The inner life of these ancient Guilds, which were in high prosperity during the fourteenth and fifteenth centuries, abounds in features of quaint and picturesque interest. The chief event of annual importance in the life of the Guild was the Election Day, with its religious services, feasts, and ceremonies. A solemn dirge or requiem was held on the Eve of the Festival for the repose of the souls of the deceased brethren and sisters of the Fraternity. The procession was lighted by numerous wax torches, garnished with "points" (_i.e._, bows) and streamers of ribbon. A frugal repast followed, consisting of a kilderkin of ale, white buns, cheese, and spiced bread. The important proceedings of the following day, that of the festival itself, began with a solemn performance of grand mass at one of the great monastic churches or at one of the larger parish churches, the musical part of the service being rendered by the Company of Parish Clerks. The brethren attended in their new liveries, and the invited guests included Priors, Abbots, noblemen, and the Mayor and Corporation, with the chief City officials. From the church they returned in the same state to the Hall to dinner, but first the chief business of the day, the election of the new Master and Wardens proceeded with all due formality. The retiring Master and Wardens entered with garlands on their heads, preceded by the beadle and by minstrels playing. Then the garlands were taken off, and after a little show of trying whose heads among the assistants the said garlands best fitted, it was found by a remarkable coincidence that the persons previously chosen were the right wearers. The oath of office was then administered; a loving cup was next brought in, from which the old Master and Wardens drink to the new Master and Wardens,
