The battle raged until the hour of vespers, when the principal inhabitants held a parley, and capitulated for a surrender. Muza had been incensed at their obstinate resistance, which had cost the lives of so many of his soldiers; he knew also that in the city were collected the riches of many of the towns of eastern Spain. He demanded, therefore, beside the usual terms, a heavy sum to be paid down by the citizens, called the contribution of blood; as by this they redeemed themselves from the edge of the sword. The people were obliged to comply. They collected all the jewels of their richest families, and all the ornaments of their temples, and laid them at the feet of Muza; and placed in his power many of their noblest youths as hostages. A strong garrison was then appointed; and thus the fierce city of Saragossa was subdued to the yoke of the conqueror. The Arab generals pursued their conquests even to the foot of the Pyrenees: Taric then descended along the course of the Ebro, and continued along the Mediterranean coast; subduing the famous city of Valencia, with its rich and beautiful domains, and carrying the success of his arms even to Denia. Muza undertook with his host a wider range of conquest. He overcame the cities of Barcelona, Gerona, and others that lay on the skirts of the eastern mountains: then crossing into the land of the Franks, he captured the city of Narbonne; in a temple of which he found seven equestrian images of silver, which he brought off as trophies of his victory.[50] Returning into Spain, he scoured its northern regions along Gallicia and the Asturias; passed triumphantly through Lusitania, and arrived once more in Andalusia, covered with laurels, and enriched with immense spoils. Thus was completed the subjugation of unhappy Spain. All its cities and fortresses, and strong holds, were in the hands of the Saracens, excepting some of the wild mountain tracts that bordered the Atlantic, and extended towards the north. Here, then, the story of the conquest might conclude, but that the indefatigable chronicler, Fray Antonio Agapida, goes on to record the fate of those persons who were most renowned in the enterprise. We shall follow his steps, and avail ourselves of his information, laboriously collected from various sources; and, truly, the story of each of the actors in this great historical drama bears with it its striking moral, and is full of admonition and instruction.
