Answer:
Name for zenith
My first master has four legs, my second master has two. My first I serve in life, my second I serve in death. Tough I am, yet soft beside. Against ladies cheeks I often reside.
I work when I play and play when I work.
I am mother and father, but never birth or nurse. I'm rarely still, but I never wander.
What is it that was given to you, belongs only to you. And yet your friends use it more than you do?
Iām grown from darkness but shine with a pale light. Very round I am and always a lady's delight.
