Certain circumstances affected the combat. Friday was the holy day of the Moslems, Saturday was the Sabbath of the Jews, of whom there were many in the Christian host, and Sunday that of the Christians, and Alfonso had already requested Taxfin that truce should be observed on these days, and the Moor had consented. But Alfonso considered himself justified in attacking at the hour of dawn on the Friday morning. He marshalled his host into two divisions, and set on. The Moorish King of Seville had asked his astrologer to cast a horoscope with the intention of discovering the fate of the day, and as this had been entirely unfavourable to the Moslems they were somewhat disheartened. But as they succeeded in withstanding Alfonso's first attack, the student of the stars cast another mystical diagram, and on this occasion found his prognostication more auspicious. The King of Seville, inspired by the favourable prophecy, sat down in his pavilion and, taking pen and parchment, dashed off the following verse, which he sent for the inspiration of his ally, Taxfin: God's anger on the Christian horde Sends cruel slaughter by thy sword, While favouring stars announce to thee And to thy Moslems victory! Taxfin was greatly inspirited by these words, and rode up and down his ranks encouraging his men, but he had not much time to do so, for King Alfonso, heading a terrific charge, dashed down on him with all the mail-clad chivalry of Spanish Christendom. A sanguinary and murderous conflict ensued. The Moslems stood their ground bravely, but the heavy cavalry of the Spaniards bore them down, and overwhelmed them on all sides. The Moorish allies of the Christian force now came into action, surrounding and hemming in the Arabs of Andalusia, and the Moslem chroniclers tell us that the darkness produced by that mass of men and horses was so great that those who fought could no longer see each other, and grappled hand to hand, as in an obscure night. At last Taxfin's forces began to retreat, and broke into disorderly rout, closely pressed by the Christian cavalry. The Moors of Seville alone stood their ground. Taxfin placed himself at the head of his reserve and, charging with great fury, threw his mounted columns directly at the pavilion of King Alfonso. This was but slightly defended, and easily fell a prey to the Moslems, with all its treasure. Alfonso, noting the advance of Taxfin, charged him in flank, and the two principal leaders were soon engaged in furious battle. The Moorish monarch rode among his men, exhorting them to constancy, and crying out that the reward of their valour would be the crown of paradise. As the result of his repeated charges the Christian host began to give way, and on the renewed attack of Taxfin's allies, who had before been beaten, fled in precipitate rout. Alfonso, seeing that all was lost, and accompanied by five hundred followers only, rode fast before the conquering Moors.
