A precious stone, as clear as diamond.
Seek it out whilst the sun’s near the horizon.
Though you can walk on water with its power,
Try to keep it, and it’ll vanish in an hour.
What is it?
With thieves, I consort,
With the vilest, in short,
I’m quite at ease in depravity;
Yet all divines use me,
And savants can’t lose me,
For I am the center of gravity.
Who am I?
I wiggle and I cannot see,
Sometimes I'm underground, and at times on a tree.
I really don't want to end up on a hook,
I turn into a person when combined with a book.
What am I?
