Little Apocolypse Response

This poem is kind of hard to interpret. It is a sad poem, mentioning death. Yet it is also very moving poem with lines such as "the robin, great warrior, above". The line "Coffins and sugar bones awash in the sudden sun."  was very interesting to me. Was this trying to say dead bodies? What are sugar bones? I also got the vibe that this poem had a religious meaning to it. "Then, from the black horizon, four horses heave up, flash on their faces." This is where the religious meaning of this poem struck me. Charels Wright paints a picture very well. You can picture the destruction and you can almost feel the distress of the situation. I reall enjoyed how real this peom was.
