Rhea

You, who lived in an abusive marriage
Your husband stole your children's love
Denied you their upbringing
But your youngest was a rebel 
He became the liberator
Zeus convinced his siblings they were fooled
He lead the uproar with thunder in his hands
He became the new king
And then, when the dust of war had settled
He remembered his dear mother
He gave her a noble retirement
Rhea - most have forgotten your name
But your son will always remember his mother
Who let him remain a rebel
