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;"
Tennyson's poem relates the myth of Tithonus, a mortal man who was loved by Eos, the goddess of the dawn. Tithonus was exceedingly beautiful and Eos took him from the mortal realm to live in her palace in the East:
So glorious in his beauty and thy choice,Who madest him thy chosen, that he seem'dTo his great heart none other than a God!
In their early state of bliss, Tithonus asked for a gift from Eos: immortality, so that he could be with her forever. Eos granted him immortality gladly, but forgot to grant him eternal youth as well. Tithonus is now condemned to age forever, far beyond the capabilities of the human body. His beauty has long since withered away with all his joy in life:
I ask'd thee, 'Give me immortality.'Then didst thou grant mine asking with a smile,Like wealthy men, who care not how they give.But thy strong Hours indignant work'd their wills,And beat me down and marr'd and wasted me,And tho' they could not end me, left me maim'dTo dwell in presence of immortal youth,Immortal age beside immortal youth,And all I was, in ashes.
In the poem, Tithonus is begging Eos to let him die. He begs her every morning before she leaves to light the sky with the dawn, and every morning, she kisses him tearfully and gives him no answer:
Let me go: take back thy gift:Why should a man desire in any wayTo vary from the kindly race of menOr pass beyond the goal of ordinanceWhere all should pause, as is most meet for all?[...]Thy cheek begins to redden thro' the gloom,Thy sweet eyes brighten slowly close to mine [...]
Lo! ever thus thou growest beautifulIn silence, then before thine answer givenDepartest, and thy tears are on my cheek.
Why wilt thou ever scare me with thy tears,And make me tremble lest a saying learnt,In days far-off, on that dark earth, be true?'The Gods themselves cannot recall their gifts.'
Release me, and restore me to the ground;Thou seëst 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.
