Final answer:
Option (C), Keats' devotion to Psyche is best interpreted as pure and enduring, reflecting the deep reverence and spiritual connection he feels towards her in his poetry.
Step-by-step explanation:
Keats' devotion to Psyche in his poetry is widely interpreted as C) As pure and enduring. This interpretation aligns with the Romantic poet's views on beauty and his approach to infusing classical elements with personal feelings of reverence and commitment.
Unlike the speaker in Wyatt's poem, who treats his love interest as a mere object of desire, or Sidney's Astrophel, who appears to be engaged in an insincere game of love, Keats' admiration for the figure of Psyche conveys a deeper, spiritual connection. This connection is evident in Keats' wish to become Psyche's priest in his ode, where he vows to be devoted to her with an everlasting worship and to create a sanctuary in his mind for her.
