For vain that feeble succour! Day by day Th’ imperial towers are crumbling, and the sweep Of the vast engines, in their ceaseless play, Comes powerful, as when heaven unbinds the deep! --Man’s heart is mightier than the castled steep, Yet will it sink when earthly hope is fled; Man’s thoughts work darkly in such hours, and sleep Flies far; and in _their_ mien, the walls who tread, Things by the brave untold may fearfully be read!
