Iron and stone are our slaves; We are liege to marble and steel; We go our ways through our sun filled days, Lifting our voices in loud self-praise-- Forgetting the Fates at their wheel. We build our bulwarks of stone, Skyscraper and culvert and tower, Till the man who now cowers, yet keen-nosed for power, Topples our monuments; In the space of a red-eyed hour. Kings of the world are we, With our jets of rocket speed, Till one heart of ice, who wouldn't think twice, Calls to us harshly to pay his high price. We were royally screwed indeed. Muscle and brain are our slaves; We are liege to iron and steel; But who shall say, tomorrow, today, That we shall not halt on our onward way To bow to the Fates at their wheel?
