In the thirteenth century, the Rue d'Isabelle was called the Fosse-aux- Chiens; and the kennels for the ducal hounds occupied the place where Madame Heger's pensionnat now stands. A hospital (in the ancient large meaning of the word) succeeded to the kennel. The houseless and the poor, perhaps the leprous, were received, by the brethren of a religious order, in a building on this sheltered site; and what had been a fosse for defence, was filled up with herb-gardens and orchards for upwards of a hundred years. Then came the aristocratic guild of the cross-bow men--that company the members whereof were required to prove their noble descent--untainted for so many generations, before they could be admitted into the guild; and, being admitted, were required to swear a solemn oath, that no other pastime or exercise should take up any part of their leisure, the whole of which was to be devoted to the practice of the noble art of shooting with the cross-bow. Once a year a grand match was held, under the patronage of some saint, to whose church-steeple was affixed the bird, or semblance of a bird, to be hit by the victor. {5} The conqueror in the game was Roi des Arbaletriers for the coming year, and received a jewelled decoration accordingly, which he was entitled to wear for twelve months; after which he restored it to the guild, to be again striven for. The family of him who died during the year that he was king, were bound to present the decoration to the church of the patron saint of the guild, and to furnish a similar prize to be contended for afresh. These noble cross-bow men of the middle ages formed a sort of armed guard to the powers in existence, and almost invariably took the aristocratic, in preference to the democratic side, in the numerous civil dissensions of the Flemish towns. Hence they were protected by the authorities, and easily obtained favourable and sheltered sites for their exercise-ground. And thus they came to occupy the old fosse, and took possession of the great orchard of the hospital, lying tranquil and sunny in the hollow below the rampart. But, in the sixteenth century, it became necessary to construct a street through the exercise-ground of the "Arbaletriers du Grand Serment," and, after much delay, the company were induced by the beloved Infanta Isabella to give up the requisite plot of ground. In recompense for this, Isabella--who herself was a member of the guild, and had even shot down the bird, and been queen in 1615--made many presents to the arbaletriers; and, in return, the grateful city, which had long wanted a nearer road to St. Gudule, but been baffled by the noble archers, called the street after her name. She, as a sort of indemnification to the arbaletriers, caused a "great mansion" to be built for their accommodation in the new Rue d'Isabelle. This mansion was placed in front of their exercise-ground, and was of a square shape. On a remote part of the walls, may still be read--
