They say that man is mighty,
He governs land and sea;
He wields a mighty scepter
O'er lesser powers than he;
But a mighty power and stronger,
Man from his throne hath hurled,
For the hand that rocks the cradle
Is the hand that rules the world.

What rules the World? (also known by The Hand That Rocks The Cradle Is The Hand That Rules The World) reported in Bartlett's Familiar Quotations, 10th ed (1919).
