Answer:
an emphasis on personal experience
Step-by-step explanation:
According to "On First Looking into Chapman's Homer" by John Keats, the poet writes a sonnet about reading George Chapman's translation of Homer in 1815. He expresses his intrigue at reading old poems and compares it to his previous reading of other literature.
Therefore, the feature of the Romantic sensibility that is expressed in the sonnet is an emphasis on personal experience.
