Doña Sancha obtained her liberty without difficulty, being even complimented by the King on her heroism, and provided with a brilliant escort on her return to Castile. Gonzalez contented himself with claiming the price agreed upon for the horse and falcon; and--the King not seeming inclined to liquidate the debt, which, owing to the long delay, amounted already to an enormous sum, or looking upon it as a pretext for hostility, the absence of which would not prevent the Count of Castile, in his then state of exasperation, from having recourse to arms--passed the frontier of Leon at the head of an army, and, laying waste the country, approached gradually nearer to the capital. At length Don Sancho sent his treasurer to clear up the account, but it was found that the debt exceeded the whole amount of the royal treasure; upon which Gonzalez claimed and obtained, on condition of the withdrawal of his troops, a formal definitive grant of Castile, without reservation, to himself and his descendants. Before we quit Burgos for its environs, one more edifice requires our notice. It is a fountain, occupying the centre of the space which faces the principal front of the cathedral. This little antique monument charms, by the quaint symmetry of its design and proportions, and perhaps even by the terribly mutilated state of the four fragments of Cupids, which, riding on the necks of the same number of animals so maltreated as to render impossible the discovery of their race, form projecting angles, and support the basin on their shoulders. Four mermaids, holding up their tails, so as not to interfere with the operations of the Cupids, ornament the sides of the basin, which are provided with small apertures for the escape of the water; the top being covered by a flat circular stone, carved around its edge. This stone,--a small, elegantly shaped pedestal, which surmounts it,--and the other portions already described, are nearly black, probably from antiquity; but on the pedestal stands a little marble virgin, as white as snow. This antique figure harmonises by its mutilation with the rest, although injured in a smaller degree; and at the same time adds to the charm of the whole, by the contrast of its dazzling whiteness with the dark mass on which it is supported. The whole is balanced on the capital of a pillar, of a most original form, which appears immediately above the surface of a sheet of water enclosed in a large octagonal basin.
