In the last stanza of the poem "Tithonus" by Lord Alfred Tennyson, what "all things" does Eos see?"Release me, and restore me to the ground. Thou seest all things, thou wilt see my grave;"
The poem is addressed to Aurora, the goddess of the dawn, who has given Tithonus eternal life but not eternal youth. So in this last stanza, Tithonus is pleading with Aurora to just let him die. Having eternal life but constantly getting older and older is not a good thing, and Tithonus just wants life to end, to leave his aged and frail body behind, and find rest in the earth, at least.
When the poem states that she "seest all things", it is probably just referring to the fact that Aurora is a goddess, an all-knowing goddess. The gods and goddesses had knowledge of much more than mere mortals did, so she was able to see all things. As the goddess of the dawn, she opened up each day, bringing sunlight to the entire earth, so that is another way that she sees all things. She probably knew also that Tithonus would regret his desire for eternal life; he has finally learned his lesson and so is imploring the person who foresaw his regret. So, as a goddess she probably can see most things, as a harbringer of dawn she covers the earth, and as a wise person, she foresaw Tithonus' regret at being immortal. Those would be my guesses for what she saw.
