"The Wedding of the Lady Theresa" is a semi-historical ballad which tells of the forced alliance of a Christian maiden to a noble worshipper of Mahoun. Alfonso, King of Leon, desirous of strengthening his alliance with the infidel, intended to sacrifice his sister, Donna Theresa, to his political necessities. He paved the way for this betrayal by pretending that Abdalla, King of the Moors, had become a Christian, and by indicating to her the benefits of a union with the pagan prince. Totally deceived by these representations, the lady consented to the match, was taken to Toledo, and wed to the Moor with much splendour. But on the day of the marriage she learned of her brother's perfidy, and when she found herself alone with the Moorish lord she repulsed him, telling him that she would never be a wife to him in aught but name until he and his people embraced the Christian faith. But Abdalla ridiculed her scruples, and took advantage of her unprotected state. As she had prophesied, a scourge fell upon him as the consequence of his wicked act. Terrified, he sent Theresa back to her brother, with an abundance of treasure, and she entered the monastery of St Pelagius, in Leon, where she passed the remainder of her days in pious labours and devotions. Sad heart had fair Theresa when she their paction knew; With streaming tears she heard them tell she 'mong the Moors must go: That she, a Christian damosell, a Christian firm and true, Must wed a Moorish husband, it well might cause her woe. But all her tears and all her prayers, they are of small avail; At length she for her fate prepares, a victim sad and pale. This ballad is no earlier than the sixteenth century, and seems to be based upon historic fact, and, as Mr Fitzmaurice Kelly points out, it confuses Almanzor and the Toledan governor Abdalla on the one hand and Alfonso V of Leon with his father, Bermudo II, on the other, and introduces chronological difficulties. Passing by the ballads of the Cid, to the subject-matter of which we have already done ample justice, we come to that of Garcia Pérez de Vargas
