The Bayeux Tapestry reveals many details related to life in the Middle Ages: motte-and-bailey castles, churches, houses, ships, medieval banquets, hounds and falcon hunts, armors, and even the appearance of Halley's comet. The art of medieval warfare is a major subject of the embroidery. The shields depicted in the tapestry indicate that the coat of arms or individual forms of recognition were not yet commonly used. The aspects of daily life and clothing are also remarkably well detailed. National fashions are included as the preference for short haircuts and shaving for Normans as opposed to the long hair and imposing mustaches of Saxons.
