Final answer:
The claim is true; the Doom Books included fines for bodily harm, such as mutilating an ear, with fines based on the injury's severity and the victim's status.
Step-by-step explanation:
According to the Doom Books, specifically the Anglo-Saxon legal codes, there were indeed monetary penalties for bodily injuries, including mutilating someone's ear during a fight. These early laws were known for their detailed injury tariffs, specifying the fine to be paid for each kind of injury inflicted upon another person. An ear's mutilation had a set wergild, which is a value ascribed to a person's body parts or to the person as a whole, depending on their social status.
The statement is true.
