When the cold light's uncertain shower
Streams on the ruin'd central tower;
When buttress and buttress, alternately,
Seem framed of ebon and ivory;
Wnen silver edges the imagery,
And the scrolls that teach thee to live and die;
When distant Tweed is heard to rave,
And the howlet to hoot o'er the dead man's grave,
Then go—but go alone the while—
Then view St. David's[2] ruined pile;
