Final answer:
Sonnet 41's upcoming event is marked by a volta that signifies a change in thought or emotion, but without the specific text referenced, the exact event remains speculative.
Step-by-step explanation:
In Sonnet 41, which is likely a reference to a Petrarchan or Shakespearian sonnet, an event that is about to occur is typically indicated by a volta, or a turn in thought between the octet (eight lines) and the sestet (six lines) of the sonnet. However, without the specific text of Sonnet 41, we can only speculate on the event as the reference to 'Sonnet 41' could pertain to different poets and anthologies.
Our understanding usually derives from the context provided by the preceding octave which sets up a situation, followed by the sestet which may present a resolution, a twist, or further contemplation. Sonnet structures generally culminate in a thematic or rhetorical shift which is essential to the sonnet's emotional impact or intellectual argument.
