Here you will find the Long Poem Cantiga de Santa Maria, No. 181 of poet Alfonso X (El Sabio)
Pero que seja a gente d'outra lei [e] descreuda, os que a Virgen mais aman, a esses ela ajuda. Fremosa miragre desto fez a Virgen groriosa na cidade de Marrocos, que é mui gran' e fremosa, a un rei que era ende sennor, que perigoosa guerra con outro avia, per que gran mester ajuda. Avia de quen lla désse: ca assi corn' el cercado jazia dentr' en Marrocos ca o outro ja passado era per un grande rio que Morabe é chamado con muitos de cavaleiros e mui gran gente miuda. E corrian pelas portas da vila, e quant' achavan que fosse fora dos muros todo per força fillavan. E porend' os de Marrocos al Rei tal conssello davan que saisse da cidade con bõa gent' esleuda. D'armas e que mantenente cono outro rei lidasse e logo fora da vila a sina sacar mandasse da Virgen Santa Maria, e que per ren non dultasse que os logo non vencesse, pois la ouvesse tenduda. Demais, que sair fesesse dos crishõos o concello conas cruzes da eigreja. E el creeu seu consello; e poi-la sina sacaron daquela que é espello dos angeos e dos santos, e dos mouros foi viuda. Wue eran da outra parte, atal espant' en colleron que, pero gran poder era, logo todos se venceron, e as tendas que trouxeran e o al todo perderon, e morreu y muita gente dessa fea e barvuda. E per Morabe passaron que ante passad' ouveran, en sen que perdud' avian todo quant' ali trouxeran, atan gran medo da sina e das cruzes y preseran, que fogindo non avia niun redea teuda. E assi Santa Maria ajudou a seus amigos, pero que d'outra lei eran, a britar seus eemigos que, macar que eran muitos, nonos preçaron dous figos, e assi foi ssa mercee de todos mui connoçuda. English The Virgin will aid those who most love Her, although they may be of another faith and disbelievers. The Glorious Virgin performed a beautiful miracle illustrating this theme in the city of Marrakech, which is large and beautiful, for a king who was then its ruler. He was waging bitter war with another king and for this reason, he was in great need of assistance from anyone who could give it to him. He was besieged inside Marrakech, for the other king had already crossed a large river called Morabe with many knights and a great army of foot soldiers. . They ran toward the gates of the city and all they found outside the walls they took by force. Therefore, those of Marrakech advised the king to go out of the city with a few good, carefully chosen . men at arms and fight it out right there with the other king and to order the banner of the Holy Virgin Mary taken out of the city and to doubt not that he would defeat the enemy at once as soon as he had unfurled it. Furthermore, they advised him to have the Christian congregation go out with the crosses from the church. He took their advice and when they took out the banner of that One who is mirror of angels and saints and it was seen by the Moors . on the other side, they were so alarmed by it that although it was a powerful army, all were soon defeated. AThey lost the tents they had brought and everything else. Many people of that ugly bearded crew died there. . They fled back across the Morabe River and although they had lost all they had brought there, such great fright of the banner and the crosses seized them that none of them drew back on the reins as they fled. . Thus Holy Mary helped Her friends, although they were of another faith, to defeat their enemies, for although they were many, they did not give two figs about them. In that way was Her mercy made manifest to all.
