Final answer:
The metaphors and similes in Tennyson's 'Morte d’Arthur' highlight the substantial significance of Excalibur to King Arthur, emphasizing its symbolic connection to his rulership and legendary status.
Step-by-step explanation:
In the excerpt from “Morte d’Arthur” by Alfred, Lord Tennyson, the metaphor and simile used most strongly emphasize the importance of Excalibur to King Arthur.
The depiction of the Lady of the Lake, clothed in “white samite, mystic, wonderful,” presenting the sword to Arthur with an outstretched arm creates a powerful visual image that frames Excalibur as more than just a weapon; it symbolizes his right to rule as well as his achievements as a monarch.
Similarly, the expectation that “wheresoever I am sung or told in aftertime, this also shall be known” shows that Arthur's legacy, tied to Excalibur, is meant to be legendary and remembered throughout history.
