Caedmon, the first poet in English whose name we know, learned the art of song in a dream. According to Bede's Historia, Caedmon was an illiterate cowherd who couldn't sing. When, during this or that merry feast, it was decided that everyone in turn would contribute a song, Caedmon would withdraw in embarrassment, maybe claiming he had to go look after the animals. One night, somebody tries to pass Caedmon the harp after dinner, and he flees to the stables. There among the ungulates he drifts off and is visited by a mysterious figure, probably God. "You must sing to me," says God. "I can't," Caedmon says, if not in these words. "That's why I'm sleeping in the stable instead of drinking mead with my friends around the fire. But God (or an angel or demon - the text is vague) keeps demanding a song. "But what should I sing?" asks Caedmon, who I imagine is desperate, cold-sweating through a nightmare. "Sing the beginning of created things," instructs the visitor. Caedmon opens his mouth and, to his amazement, gorgeous verses praising God pour forth.
