Final answer:
The Bayeux Tapestry, an important piece of Norman, Romanesque art, provides insight into Harold's Oath and its significance in the Norman conquest of England in 1066.
Step-by-step explanation:
The Bayeux Tapestry is an important piece of Norman, Romanesque art that depicts the events leading up to the Norman conquest of England in 1066. While the tapestry does not specifically mention Harold's Oath, it does provide evidence of a feudal pledge of fealty from Harold Godwinson to William of Normandy. This pledge allowed William to claim that Harold had pledged allegiance to him, justifying his invasion of England.
The Bayeux Tapestry also portrays the sacred reliquaries held by Harold, highlighting their importance in the Norman conquest. These reliquaries were believed to possess sacred powers and were often used by leaders to gain legitimacy and support.
As for the most sacred of sacred oaths, the tapestry does not provide specific details. However, it does capture the solemn and ritualistic nature of oaths, emphasizing their significance in medieval society.
Lastly, while the Bayeux Tapestry does not explicitly mention Harold breaking his oath, it does depict his death at the Battle of Hastings, where he fought against William of Normandy. Harold's death ultimately led to William's victory and his establishment as the king of England.
