What metaphors are used in Two Poems for T. by Cesare Pavese?

In Lines 27—28, the poem summarizes the aspects of T. that have been mentioned already. She performs simple tasks, such as walking, and she keeps quietly to herself, waiting. While the idea of her being "earth" has already been mentioned twice, the poem returns to using "blood" as a metaphor for the physical aspect of humanity, and joins this with the spiritual aspect by saying that T's blood and love are the same thing.
