Charles overran the whole of the north of Spain with his victorious army. From Catalonia to Galicia, and extending to the line of the Ebro, he was everywhere received by, rather than took possession of, cities and fortresses. Arriving at Compostella, he paid a devout visit to the sepulchre of St. James, according to his promise, and had baptised there those of the Galicians who had forsaken the faith of their forefathers for the service of Mahomet. He established priests of the Holy Church in all the chief towns of Spain, and assembled in the month of July a council of sixty bishops and a parliament of peers, by whom it was decided that all the archbishops, bishops, kings, and princes of Spain and Galicia, present or future, should recognise the authority of the Archbishop of Compostella. The church was dedicated to St. James, Turpin officiating. It was endowed by means of a tax of four deniers per annum imposed upon the innkeepers, and was released from all feudal service. The King also declared it to be his wish that all the bishops of the country should be ordained, and all the kings crowned, by the archbishop of the diocese.
In this way the King discharged his obligation to the saint. This done, he pursued his route to the southern extremity of Spain, now known as Cape Finisterre. There, finding he could advance no further, he flung his lance into the sea, and returned thanks to Heaven and St. James for having aided him to bring his expedition to a successful issue. The gold and silver which the Emperor brought back with him from Spain enabled him to restore and found many churches—to wit, one to Our Lady at Aix-la-Chapelle, and also of St. James; a second of St. James at Beziers; a third at Toulouse; a fourth in Gascony, between the village of St. Jean de Sorgeat and Ax; and, finally, one at Paris, between the Seine and Montmartre, of which nothing remains but the lofty tower known as the St. James’s Shambles. The Emperor divided his new provinces into two Marches, called those of Septimania and Gascony. The first, which consisted of Catalonia proper, had its capital at Barcelona; the second, embracing Navarre and Aragon, had Saragossa as its seat of government. To Louis of Aquitaine, Charlemagne’s son, was committed the task of keeping the country in submission as far as the Ebro.
