"Each one of the men of the commune will be faithful to his con-juror, and will give him aid and advice, according to what justice will dictate him"--the Amiens and Abbeville charters say. "All will aid each other, according to their powers, within the boundaries of the Commune, and will not suffer that any one takes anything from any one of them, or makes one pay contributions"--do we read in the charters of Soissons, Compiegne, Senlis, and many others of the same type.(40) And so on with countless variations on the same theme. "The Commune," Guilbert de Nogent wrote, "is an oath of mutual aid (mutui adjutorii conjuratio) ... A new and detestable word. Through it the serfs (capite sensi) are freed from all serfdom; through it, they can only be condemned to a legally determined fine for breaches of the law; through it, they cease to be liable to payments which the serfs always used to pay."(41) The same wave of emancipation ran, in the twelfth century, through all parts of the continent, involving both rich cities and the poorest towns. And if we may say that, as a rule, the Italian cities were the first to free themselves, we can assign no centre from which the movement would have spread. Very often a small burg in central Europe took the lead for its region, and big agglomerations accepted the little town's charter as a model for their own. Thus, the charter of a small town, Lorris, was adopted by eighty-three towns in south-west France, and that of Beaumont became the model for over five hundred towns and cities in Belgium and France. Special deputies were dispatched by the cities to their neighbours to obtain a copy from their charter, and the constitution was framed upon that model. However, they did not simply copy each other: they framed their own charters in accordance with the concessions they had obtained from their lords; and the result was that, as remarked by an historian, the charters of the medieval communes offer the same variety as the Gothic architecture of their churches and cathedrals. The same leading ideas in all of them--the cathedral symbolizing the union of parish and guild in the, city--and the same infinitely rich variety of detail.
