Andrew Lang (1844 – 1912) was a Scots poet, novelist, literary critic, and contributor to the field of anthropology. He is best known as a collector of folk and fairy tales. The Andrew Lang lectures at the University of St Andrews are named after him. Lang was also a prolific author of works both fiction and non; he wrote his own fairy tales such as Prince Prigio and Prince Ricardo of Pantouflia, and wrote numerous historical texts. 'The Black Thief And Knight Of The Glen' is a fairy-tale that was collected and retold by Andrew Lang. The fairy-tale tells us about a royal family that has three sons. One day a grief comes to the kingdom for the queen who is loved by rich and poor finds herself on her deathbed. She tells the king that he can be free to marry again after her death but he in return he must lock the three sons in a tower on an island until they are grown up.
