This simple legend belongs to the tenth century; and notwithstanding that the opinion of this Benedictine monk may appear strange nowadays, yet it must be acknowledged that he was only conforming himself to the opinions laid down by certain theologians. In 817, the Council of Aix-la-Chapelle decided that such delicate nourishment could scarcely be called mortification as understood by the teaching of the Church. In consequence of this an order was issued forbidding the monks to eat poultry, except during four days at Easter and four at Christmas. But this prohibition in no way changed the established custom of certain parts of Christendom, and the faithful persisted in believing that poultry and fish were identical in the eyes of the Church, and accordingly continued to eat them indiscriminately. We also see, in the middle of the thirteenth century, St. Thomas Aquinas, who was considered an authority in questions of dogma and of faith, ranking poultry amongst species of aquatic origin. Eventually, this palpable error was abandoned; but when the Church forbade Christians the use of poultry on fast days, it made an exception, out of consideration for the ancient prejudice, in favour of teal, widgeon, moor-hens, and also two or three kinds of small amphibious quadrupeds. Hence probably arose the general and absurd beliefs concerning the origin of teal, which some said sprung from the rotten wood of old ships, others from the fruits of a tree, or the gum on fir-trees, whilst others thought they came from a fresh-water shell analogous to that of the oyster and mussel. As far back as modern history can be traced, we find that a similar mode of fattening poultry was employed then as now, and was one which the Gauls must have learnt from the Romans. Amongst the charges in the households of the kings of France one item was that which concerned the poultry-house, and which, according to an edict of St. Louis in 1261, bears the name of _poulaillier_. At a subsequent period this name was given to breeders and dealers in poultry (Fig. 92). The "Ménagier" tells as that, as is the present practice, chickens were fattened by depriving them of light and liberty, and gorging them with succulent food. Amongst the poultry yards in repute at that time, the author mentions that of Hesdin, a property of the Dukes of Luxemburg, in Artois; that of the King, at the Hôtel Saint-Pol, Rue Saint-Antoine, Paris; that of Master Hugues Aubriot, provost of Paris; and that of Charlot, no doubt a bourgeois of that name, who also gave his name to an ancient street in that quarter called the Marais.
