Hoists the strong sail to cross the hoary sea,
Ploughs the unwearied earth, yokes the wild steed
And the untamed mountain-bull; thought that contrives
Devices that can cure all ills but death:
Of all strong things none is more strong than man;
Man that has learned to shield himself from cold
And the sharp rain; and turns his marvellous arts
Awhile to evil; and yet again, to good;
Man that is made all-glorious with his city
When he obeys the inviolable laws
