I expect it figured out by the time I wake up...
The Riddle:
Covered with sackcloth vile they seemed to me,
And one sustained the other with his shoulder,
And all of them were by the bank sustained.
But taken from me was this drowsiness
Suddenly by a people, that behind
Our backs already had come round to us.
Even as our eye did not uplift itself
Aloft, being fastened upon earthly things,
So justice here has merged it in the earth.
Appeared to me with laden and living boughs
Another apple-tree, and not far distant,
From having but just then turned thitherward.
And I, who stood intent upon beholding,
Saw people mudbesprent in that lagoon,
All of them naked and with angry look.
Shadows borne onward by the aforesaid stress.
Whereupon said I: Master, who are those
People, whom the black air so castigates?
And he to me: The grievous quality
Of this their torment bows them so to earth,
That my own eyes at first contended with it;
If its not figured out by the (i was gonna say morning, but it is for me already), I will give a single clue.
