Answer:
We are five little objects of an everyday sort. You will find us all in a tennis court.
I fly, yet I have no wings. I cry, yet I have no eyes. Darkness follows me. Lower light I never see.
Halo of water, tongue of wood. Skin of stone, long I've stood. My fingers short reach to the sky. Inside my heart men live and die.
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 within an hour.
It comes only before, it comes only after. Rises only in darkness, but rises only in light. It is always the same, but is yet always different.
Iām grown from darkness but shine with a pale light. Very round I am and always a lady's delight.
