Final answer:
Merlin's teachings to Arthur encompass the arts of kingship, aspects of wisdom, justice, and magical practices, reflecting the comprehensive education expected of a monarch during medieval times.
Step-by-step explanation:
During his tutoring, Merlin teaches Arthur a range of subjects including the arts of kingship, and in certain stories, magical practices and the worship of the gods. These teachings were seen as integral to the formation of a prince or future king, aligning with the philosophy that rulers should be well-versed in various disciplines, such as leadership, justice, and piety. The education of a prince also included literature, as reflected by the references to poetic works such as those by Tennyson and the legendary relationship between Arthur, Sir Lancelot, and Camelot. In a broader historical context, this reflects the medieval ideals of the well-rounded education of a monarch, which would include wisdom in civic matters, knowledge of religious or magical practices, as well as military prowess and chivalry.
