Overall, "The Burial of the Dead" makes me think of "O Fortuna" by Carl Orff, they're both dreary with undertones of change, cycles, and the endless march of time, though, "O Fortuna" is much more cynical where "The Burial of the Dead" seems to hinge on the hope that things will get better. When it comes the highlighted area, the way Eliot described winter made me think of a wasteland covered in snow, but then shows how things start to change so suddenly so that it's summer again; bringing up the cycle that life goes through. In "O Fortuna", one of the lines (translated) is:
Hateful life
First oppresses
And then soothes
As fancy takes it;
Poverty and power
It melts them like ice.
This line is why I chose "O Fortuna", because it shares the idea of life getting hard and oppressive (oppressing what? Dreams, memories, feelings?) and harsh (like winter) but then soothes the pain and oppression with warmth. But never does the song suggest that things will say prosperous, in fact it emphasizes that life gets easier and harder as fate dictates.
In "O Fortuna", fortune seems to be some sort of sentient/god like being who is blamed for all of the hardships mentioned in the poem, unlike in "The Waste Land", where a lot of the blame seems to be put on the cycle that life goes through. The original poet suggests there's a certain amount of helplessness for humans where they are held at the "fancy" of fate and the changes it might go through and the song itself mentions all of the cycles life (and it's inhabitants) go through with an emphasis on the harsher parts of life (poverty, health issues, death). With "The Waste Land", Eliot seems to cycle through the positive and negative parts of certain speakers lives and the harsher periods of nature, encapsulating the cycles that the world goes through that "O Fortuna" merely hinted at. When it comes to which one is more optimistic, I'd go with "The Waste Land" because there's always a lingering hope that something good is just around the corner in the poem, that something good could grow. In the end of the poem, a speaker asks another if something is growing from the corpse that was planted, "'Has it begun to sprout? Will it bloom this year?'". Meanwhile, "O Fortuna" ends with:
So at this hour
Without delay
Pluck the vibrating strings;
Since Fate
Strikes down the strong man
Everyone weep with me!
The poem suggests that there's nothing anybody can do to stop the death that is approaching everyone. There’s no chance of saving nor does it provide any hope that things will turn out alright like Eliot did in “The Waste Land” and his suggestions of growth coming out of the frost.
