What do you call a work of literature that idealizes rural life?

Pastoral

Pastoral is a mode of literature which occurs in many types of literature like poetry, drama, and elegy.

It was defined in three ways by Terry Gifford, a prominent literary theorist, In his critical book Pastoral:

1)discuss life in the country and in particular the life of a shepherd

2)describes the country as rural, with an implicit or explicit contrast to the urban

3)depicts the country life with derogative classifications.  

(you didn't attach a copy of the poem, but i'm answering as best as i can)

since a simile compares two unlike things using like or as, it kind of gives an item the ability to do something it can't.

example: "the player was like a tiger on the field"

in this sentence, the simile conveys the idea that the player was fast and strong, like a tiger.
