The bard once amused and puzzled the court by entering the hall as a blind boy led by a greyhound, playing on his harp, and demanding as recompense to be allowed to carry the king's banner in an approaching battle. Being refused on account of his blindness he vanished, and the king of Brittany mentioned his suspicions that this was one of Merlin's elfin tricks. Arthur was disturbed, for he had promised to give the child anything except his honor, his kingdom, his wife, and his sword. However, while he continued to fret, there entered the hall a poor child about eight years old, with shaved head, features of livid tint, eyes of light gray, barefooted, barelegged, and a whip knotted over his shoulders in the manner affected by horseboys. Speaking and looking like an idiot, he asked the king's permission to bear the royal ensign in the approaching battle with the giant Rion. The courtiers laughed, but Arthur, suspecting a new joke on Merlin's part, granted the demand, and then Merlin stood in his own proper person before the company. He also seems to have taught people many things in real science, especially the women, who were in those days more studious than the men, or at least had less leisure. For instance, the legend says of Morgan le fay (or la fée), King Arthur's sister, "she was a noble clergesse (meaning that she could read and write, like the clergy), and of astronomy could she enough, for Merlin had her taught, and she learned much of egromancy (magic or necromancy); and the best work-woman she was with her hands that any man knew in any land, and she had the fairest head and the fairest hands under heaven, and shoulders well-shapen; and she had fair eloquence and full debonair she was, as long as she was in her right wit; and when she was wroth with any man, she was evil to meet." This lady was one of Merlin's pupils, but the one whom he loved most and instructed the most was Nimiane or Vivian, already mentioned, who seems to have been to him rather a beloved younger sister than anything else, and he taught her so much that "at last he might hold himself a fool," the legend says, "and ever she inquired of his cunning and his mysteries, each thing by itself, and he let her know all, and she wrote all that he said, as she was well learned in clergie (reading and writing), and learned lightly all that Merlin taught her; and when they parted, each of them commended the other to God full tenderly." The form of the enchanter Merlin disappeared from view, at last--for the legends do not admit that his life ever ended--across the sea whence he came.
