explain the metaphor in the following quote "truly i could have sworn/It would be long indeed ere i came hither/ Under that hail of threats you rained on me" what effect doe the comparison have on creons characterization ?

The metaphor is involved in the phrase "hail of threats" - the comparison here is "a barrage of threats" being compared to a "barrage of hail." The threats are the literal part of the metaphor; the hail is the figurative. The metaphor makes the reader think about the effect that a huge amount of hail could make if it hit something real - hail, for example, easily damages or makes dents in a roof or a vehicle.
