A Dream of John Ball (1888) is a novel by English author William Morris about the English peasants' revolt of 1381 and the rebel John Ball. Like the novels close contemporary - A Connecticut Yankee in King Arthur's Court (1889) by Mark Twain - it describes a dream and time travel encounter between the medieval and modern worlds. However unlike Twain's vision of a violent and chaotic "Dark Age", Morris describes a positive image of the Middle Ages, seeing it as a golden, if brief, period when peasants were prosperous and happy and guilds protected workers from exploitation.
