The narrator of an Alan Seeger poem "has a rendezvous" with this character 
The narrator of an Alan Seeger poem "has a rendezvous" with this character "at some disputed barricade". A poem addressed to this character describes this character as "slave to fate, chance, kings, and desperate men", and ends by telling this character "thou shalt die". Another poem about this character describes how "[we] passed the setting sun / Or rather, he passed us". That poem ends with the image of horses' heads pointed toward eternity, and describes a carriage ride past a school with children playing at recess. For 10 points, name this personification that "kindly stopped for" Emily Dickinson because she could not stop for it.
