I guess solitary reaper was a time traveller who was telling about corana virus spread and how it created panic but gradually everything was wonderfully settled. I donot want to reconstruct the poem.
The Solitary Reaper” is a lyric by English Romantic poet William Wordsworth, and one of his best-known works. … The poet orders or requests his listeners to behold a young maiden reaping and singing to herself. The poet says that anyone passing by should either stop or gently pass as not to disturb her.Author: William Wordsworth
The poet has an idea that she is singing about some pandemanic but he is not able to interpret her words .
