"And above the ships are palaces of brown, black-bearded chiefs, And below the ships are prisons, where with multitudinous griefs, Christian captives sick and sunless, all a labouring race repines Like a race in sunken cities, like a nation in the mines. They are lost like slaves that sweat, and in the skies of morning hung The stair-ways of the tallest gods when tyranny was young. They are countless, voiceless, hopeless as those fallen or fleeing on Before the high Kings’ horses in the granite of Babylon. And many a one grows witless in his quiet room in hell Where a yellow face looks inward through the lattice of his cell, And he finds his God forgotten, and he seeks no more a sign— (But Don John of Austria has burst the battle-line!)"
