Final answer:
Sir Agravaine is the brother of Arthur who rarely speaks. His character is known for its shadowy presence in Arthurian legends, contrasting with his more outspoken brothers like Sir Gawain.
Step-by-step explanation:
The brother of Arthur who rarely speaks is Sir Agravaine. In Arthurian legends, there are multiple brothers, but Agravaine is less vocal compared to others like Sir Gawain.
Agravaine is known for his negative traits and often being in the backdrop of Arthurian tales. Although he plays a significant role in the downfall of Sir Lancelot and Queen Guinevere's affair, his character seldom engages in extensive dialogue. This characteristic makes him a lesser-known figure in the stories of King Arthur and his Knights of the Round Table. His quiet demeanor stands in contrast to his brothers, who typically have more speaking roles or heroic portrayals in the legends. Arthurian literature has been a rich source of study, especially in exploring the dynamics between the silent Agravaine and his more celebrated siblings.
Understanding the role of Agravaine is essential to grasp the intricate family relations and court dynamics in Arthurian lore. His character adds to the multi-faceted portrayals of knights that vary from valiant heroes to intricate, flawed individuals.
