Let us begin by considering them in those places where they were held firmly in check. The authority which weighed on them was exerted in several directions at which we will glance. In the first place, this authority attempted to regulate the conditions of labour, to fix its hours and its price. It forbade work on certain days, though it is true that it consented to many exceptions. At Rome, where religious festivals were naturally very numerous, the Pope authorized the wine-sellers and innkeepers to serve travellers, though not inhabitants of the town, on such days; the farriers to shoe horses on condition that they did not make new shoes; the barbers to dress wounds but not to shave; the grocers and fruiterers to open their shops without displaying their goods; the butchers to hang their meat, so long as it was covered up; the shopkeepers in general to leave the doors of their shops half open for the sake of ventilation.[70] In other words, trade was allowed _sub rosa_. The intervention of the lord in these matters was so habitual that it caused no surprise. John II. of France, in his famous ordinance of 1355, proclaimed in 227 articles a maximum tariff for merchants' goods and the wages of the workmen. The Statute of Labourers in England in 1349 had similar objects. The authorities interfered also in judicial matters. When there was a dispute between two guilds (and this, unfortunately, was of frequent occurrence) the case came under the jurisdiction of the lordly, communal, or royal tribunal; in Paris the matter went before the king's provost, and in case of appeal, to the _Parlement_. But if the trade was held in fee, _i.e._ if it was under the protection of a master who held it in fee, it was he who settled the difference. Thus long wars were waged between barbers and surgeons; at first united in one body, they wished later on to be separated; but the surgeons wanted to keep the monopoly of surgical operations, and against this the barbers protested. Now the head of the trade was the king's barber and first _valet de chambre_; and in 1372 he inspired an ordinance, which reserved to the barbers the right to "administer plaisters, unguents, and other medicines suitable and necessary for curing and healing all manner of boils, swellings, abscesses, and open wounds." This, however, did not prevent the quarrel from lasting several centuries longer.[71] There were many other causes which led to lawsuits.[72] The guild might go to law with individuals over the possession of a house or a field, or have difficulties with the tax-collector. Often, too, the causes of dispute lay within itself and arose between officers and masters, who claimed to have been unjustly accused of wrong-doing. In all these cases it was invariably the rule to apply to the head of the craft or to the representatives of the competent authority (provost or seneschal).
