Final Answer:
The question of whether King Arthur or Mordred breaks the parley depends on the interpretation of Arthurian legends, as different versions present varying narratives.
Step-by-step explanation:
In Arthurian legends, the story of the parley between King Arthur and Mordred often involves a crucial moment of negotiation or confrontation. The outcome of the parley, including whether it is broken and by whom, can differ in different retellings and adaptations of the Arthurian myth.
In some versions, the parley may be broken by Mordred, driven by treacherous motives or a desire for conflict. Alternatively, there are renditions where King Arthur is portrayed as the one who breaks the parley, perhaps due to mistrust or a realization that peace is unattainable.
The diverse nature of Arthurian legends means that there is no singular answer to whether King Arthur or Mordred breaks the parley, and interpretations may vary based on the specific source or adaptation of the legend.
