Among the obligations originally imposed upon this convent, was that of giving a dinner annually, on Trinity Sunday, to such of the inhabitants of the parish of Vaux-sur-Saulles and their domestics, as had resided there a year and a day. The repast was served up within the abbey walls, and in the following manner:--After the guests had washed their hands in a tub of water, they seated themselves on the ground, and a cloth was spread before them. A loaf, of the weight of twenty-one ounces, was then given to each individual, and with it a slice of boiled bacon, six inches square. To this was added a rasher of bacon, fried; and the feast concluded with a basin of bread and milk for every person, all of them having likewise as much beer and cider as they could drink. The dinner, as may naturally be supposed, lasted from three to four hours; and it will also not be difficult to imagine, that the entertaining of such a motley throng on such a day, could not fail to be attended with great annoyance to the nuns, and with various inconveniences. The convent had therefore, from a very early date, endeavored to free themselves from the obligation, by the payment of a sum of money; and, in times of war, the town of Caen had occasionally interposed, and forced the people to accept the composition, from an apprehension, lest the enemy should gain possession of the fort of the Trinity, by introducing themselves into it among the authorized guests. It appears that, in 1429, the abbess purchased an exemption at the price of thirty livres, a sum equivalent to thirty-seven and a half quarters of corn, at a time when wheat sold for two sols the bushel; and twenty-two years subsequently, Charles VII. then King of France, granted his letters patent, abolishing the dinner altogether, upon condition of a like sum being annually paid to the parochial chest. To the abbey church of the Trinity were attached several chapels, as well without as within its walls: the most remarkable of these was that of St. Thomas, generally known by the name of _St. Thomas l'Abattu_, in the suburb of St. Giles. It was, in its original state, an hospital, and was called the Hospital of St. Thomas the Martyr in the fields, whence De la Rue infers that it was built in commemoration of Thomas-à-Becket, and was probably erected immediately after his canonization in 1173. Huet, on the contrary, tells us, that it had existed "from time immemorial;" and Ducarel, who has described and figured it,[53] appears to have also regarded it as of very high antiquity. The gradual disappearance of leprosy had caused it to be long since diverted from its original purpose. In 1569, it was pillaged by the Huguenots; and, as no pains were taken to repair the injuries then done, it continued in a state of dilapidation, imperceptibly wasting away, till the period of the revolution, when it was sold, together with the other national property; and even its ruins have now disappeared.
